Hey - wanted to drop in and tell ya I love the game idea. I'm going to try to give my impressions as I play...
Level 1 - the good: (this goes for the whole thing) - love the animation. It looks like you have a ways to go with the art, but I can see this looking great. You got a pretty decent character controller with Unity physics, the weight of the character feels pretty good. Not sure if you know of this guy's controller, but may be worth a look if you're still having issues:
http://forum.unity3d.com/threads/223395-WIP-Platformer-Pro the not so good: This is just my opinion, but way too many leaps of faith. I would love to see levels designed around being able to see where you're going to land so the game is figuring out the maze/puzzles without dying to do it (unless you deserve it). It sucks killing yourself multiple times just to find the correct path.
The jump where your head hits the spikes is annoying... you have to stand in EXACTLY the right spot to get under it.
It seems like you get stuck in the angles that are a little bit past 90 degrees (like the little stair at the exit).
Level 2 I just fell pretty much into the exit hole.
Level 3 Another leap of faith fest. I also couldn't get past this, as I got stuck in a loop after I fell of the right hand side - It dropped me into the spikes in an endless loop.
FUN. Did you have fun playing? yes/no? why?
I can definitely see the promise of fun. Keep with it, this will be great!
The curved regions, are they still a mystery after playing the first and second levels? Do you know what they do? Can you tell if a region is curved without stepping into them?
The third level was a little bit weird on the J section where you could jump down (mushroom is on wall to the right), but couldn't rotate the world back and use the mushroom to get back up. You pretty much had to commit suicide. My feeling is there should always be a way out. Otherwise, it was pretty understandable that the world turns...
Aything else you want to share :D
Nope, hope this helps, can't wait to see more progress!
