Hi all! I'm Gionathan at Neutronized.com. I'd like to show you the last flash browser game from Neutronized called Slime Laboratory. Slime Laboratory is a physics-based platform where you take control of a slime which wants to get out from the lab.

The slime can perform a lot of different actions: you can stretch your slime and turn it very slick to get inside narrow pipes, you can absorb more slime to get bigger and destroy walls and you can also split in two different little slimes.

Inside the lab there are a lot of traps you have to face like lasers, high voltage current, spinning spikes, spinning pipes and much more. The game also features special levels with a different gameplay where you have to escape from emerging acid.

The idea behind the game took inspiration from great games like Mercury Meltdown and Gish.

Hope you have fun with Slime Laboratory!

this is awesome :D great work!

notes:

you hit a massive difficulty spike in the first purple goo rising level. the bit where you have to jump up the tiny ledges before the spinning boxes, is very tough for a beginner, mainly because half the time he fails to jump the right height and you fall back into the goop. I don't know why he was jumping half-height sometimes but it was pretty frustrating. I think you ought to put a checkpoint at the top there before the boxes at least..

if the jump-height thing on tiny ledges is intentional, I suggest you give the player some tiny ledges to jump up in a non-stressfull situation so they can learn them without being killed for making 1 mistake

I think in general the placing of checkpoints is a little stingy, since some of the platforming is pretty tough (well, for me it was)

well having said all that I think it's a great game, love the graphics in particular- really vibrant. I think if I had any minor crits there, I think the checkpoint pad isn't big and bold enough, considering how important it is- it's really just a little green circle. Imo a checkpoint element should really stand out.

Goo-d stuff! teehee

This is pretty fun. I agree with the user above me. The rising goo levels are a crazy difficulty spike. I stopped playing during the second one out of frustration. They would seem better as challenge maps after the fact. Still, this is a great game, good job.

i feel more like a ninja than a slime when it come to the rising acid level...

nice game, but the difficulty kick up too fast after level 3, but some later level are kinda easier than the earlier.

and i like to stuck halfway when i squeeze the slime through vertical narrow path :lol:

Hey, thanks for the feedbacks!

Yes, I see how the difficulty curve might increase too much during the first levels.

Regarding the checkpoints, I tried to put a maximum of 3 checkpoints per level and to have an equal number of traps between each of them.

Thanks again!

well, it's your call :) but if you want people to get to the end of it, I'd still think about making it a little easier. Don't forget you get really good at playing your own game!

Wow this is actually really neat, I like the mechanic you have for going through small tunnels.
The movement is nice though I kind of wish he were a bit more mobile on walls, reaching that jump on level 3 was difficult I had to use the swinging platform to get up there.

Would be nice if he could even just walljump.

I was working on a similar game concept back in 2009 where you collect slime, get bigger and jump higher.
Except in my version I had color types which changed your immunity to certain hazards and made normally non-threatening things into hazards.
And the objective was to retrieve as much slime as you could and deposit it without losing it all on the way back.
Here's a gameplay video (http://www.youtube.com/watch?v=IKxK_37yHaw) if your interested in seeing it in action.

But I like this games mechanics, I was a little turned off by the whole gravity switch thing, I kind of wished the slime could just use the walls and ceiling better but I guess thats just because of how my slime got around.

None the less interesting game, the individual eyeballs floating inside him is the best part, remind me of googly eyes.
Also the slime has some interesting properties to it, such as if you hit a small hole going quickly you leave some part of you behind it's got a nice smiley feel to it.

Well done.

The gameplay video is very cool. I like the blob's physics and the color mixing.

The wall jump, or maybe a sticky wall, was something which really tempted me during the development of the game. Then I decided to skip it since the development was taking too much time.

I'm really proud of the eyes of the slime and happy you noticed them. They required extra programming and testing because they were messing around and getting in wrong positions all the time but now I think they are giving more personality to the blob!

cool game!
just finished it...
was a lot of fun!  :)

@bones
nice concept

I've managed to get through a couple levels of this in free moments at work. It's definitely a lot of fun! I'd kind of have to agree above about the difficulty curve, though.

The physics make it a lot of fun, and it really does have a 'slimy' feel. The only thing that bothered me was when I try to jump and I'm touching a wall I don't get anywhere, which was frustrating when I was jumping away from the acid in the 4th level.

Yes, that's a good point. I think this is the most frustrating problem of the game.
I was thinking about ways to avoid that, maybe by reducing the friction or giving an extra vertical push when the whole slime is touching the wall.

I think even giving the player a reduced vertical jump off the wall.
Just enable jumping on the wall, so they could travel from edge to edge while sliding down it.

Unless that's more difficult then it sounds?

You're right, I forgot about the wall jump. That might be the best solution to avoid the slime getting stuck on the wall.

This is just amazing. :beer:  Definitely one of the best flash games I have ever seen.

this

I had trouble on that level also I couldn't get past that jump after the swinging bars no matter what - after 5 tries I gave up.

but overall it's an interesting game  :handthumbsupR: on the presentation.

Just finished level 8 (ridiculously fun one) but it reminded me of something that set me back in a few levels.

I like the checkpoint system, but I don't like that the objects in the level don't reset. This is especially noticeable when you're running from the purple acid. Sometimes the timing doesn't work out and there's no way to avoid a laser when you're jumping from the slime and you're forced to die repeatedly until it syncs up enough to be passable again. Similar things can happen with swinging platforms, etc.

One of my issues with swinging platforms was how the player got shifted back to the opposite side your moving, it made it rather difficult to jump off them.

i've just played through the game...and recorded it. :)
it's not a perfect playthrough though. rather a laid-back one.
so you will also see those bits that required many tries.

Cool playthrough, I really appreciate it. :)


You're right, that's another good point. I noticed this these days while playing the game again. I'm sure it would have been better to reset to the original position and speed or at least decrease their speed after the blob respawns.

a better playthrough (http://www.youtube.com/watch?v=J1UsuhsS5sI)

Consider adding a way to restart the current level. I wanted to restart it so I could take some of the 'floppy disks' I missed, because I had no way of going back to previous areas of the level. I'm an OCD kinda guy.

Besides that, great game, good job!
