OK, wow, this is going to be a long one. I went ahead and had a bit of a playthrough of your game, it really sucked me in. Here's everything that I wrote down as I played, I hope it helps!
==== Main Menu ====
Fullscreen option would be nice.
No Widescreen?
Like that I don't need to register.
==== Tutorial ====
Oh! A treasure chest. Always nice.
Awww yeah, gun loot.
Character animations are pretty sick.
Love the exploding background for the intro.
Music fits nicely.
First enemy doesn't move, good for target practice while starting out.
GRENADES!
Awesome Grenade testing area.
- Wasn't sure what the yellow barrior was all about at first.
Diagonal shooting works great
Tutorial Boss was pretty easy, but not overly so.
- Good first engagement with a real enemy.
I like that weapons equipment is shown side by side with what's dropped.
- Would be nice if it shows Stat ups and Downs
Inventory's a bit messy
- Would be great if you could use your mouse.
I switched my weapon, but the tutorial won't let me through?
- Can't move to the right...
- Can't move to the left...
- Refreshing the game...
- There should be a browser warning if you try to refresh the game.
- Could prevent accidental data loss.
==== Spawn Room? ====
Refresh started me somewhere else.
- Looks like I missed a good chunk of the tutorial?
- Took the only class that was available to me.
I like his shift move, but I think the arrow you use is backwards.
- You should be using the arrow as a direction, meaning if you press back, you should expect to move back, not forward.
- Consistancy here is important so controls don't get mixed up.
Like the grenade kick animation on this guy, looks sweet.
Music is really chill.
===== Into the Fire Forest! =====
Killed an enemy, got a Max HP up? Intresting...
I keep pressing the wrong button for my gun, end up using my grenade instead.
- Feels reversed, I'd rather have S be my main and D be my grenade.
- Rebindable keys someday?
This music is REALLY epic.
Someone ran ahead of me, now I don't see enemies anymore.
- Did they kill them all?
- How long does it take for respawns?
Really like this floating rocks section
- Looks cool and is a neat platforming idea!
- Camera up-scrolling could be a bit smoother.
Still no enemies...
- Respawning REALLY needs to be more frequent.
Finally found one!
- Movement speed and jump height increased? Awesome!
Found a chest full of new loot for my class.
- Love the difference in guns, have a splitting shot now!
Finding some really in-depth stat incrases through drops.
- Just found crit base-damage. It's a neat idea, way cooler than levelups!
Inventory full already?
- That was really quick, is 8 slots enough?
- Granted I'm a loot-whore, but still...
Lost connection to server! NOO!
Account is currently in use... wait a minute or two...
===== Two Minutes Later ====
Back in, but I'm in the Lobby Area it seems...
All stats remain, but I didn't get to pick up those goodies.
EC is money? Huh, very little of it dropped.
- Shouldn't all enemies I kill be worth at least one EC?
- If Currency is RNG based, it could lead to a bad time for some people.
Is there anywhere I can sell my loot?
- Guess I'll store some of it...
- Dropped the rest.
==== Fire Forest Again ====
Oh, just saw the tip that says double tapping uses my special in that direction.
- Still feels reversed, but good to know.
I see now, these areas are all randomized. Neat!
Would be nice if by holding down for a while the camera panned down.
- Would save me from taking unknown falls.
Level design is pretty awesome! Hard to believe it's randomized!
First boss was "easy", but engaging, so it's a happy medium for a first boss.
- Dropped some sweet loot too.
- Loot stacked on top of each other, hard to tell what's what.
Just pressed Esc for the first time and discovered the Graphics menu.
- Put that in the main menu at the start, alot of people will be intersted in going Widescreen immediatly.
- Widescreen should be the default anyway
SO much better in 1920x1080, why isn't this default!?
Also discovered the controls.
- I COULD HAVE BEEN USING MY CONTROLLER THIS WHOLE TIME!?
- (Doh)
Controller mode works great, this should be FRONT AND CENTER functionality.
- "Controller is Recommended" on the title screen would be most welcome.
Wait, that last guy wasn't a boss? (The Fireball Spitter Dude)
- More level, huh, neat.
I love this tree guy that's spawning the dinosaurs. Great enemy design.
I'm realizing now that I have a penetrating weapon and a multi shot weapon how much I'd love to easily be able to switch between the two.
- A weapon swap system for 2 specific weapons would be pretty sweet for situational stuff.
- One weapon that's better at single target, one that's better at multi target.
Got to the first boss FOR REAL
- He's really tough.
- Pretty sure if I die I lose everything.
Teleported home with 6 HP.
- Looked like a good fight, but didn't want to lose it all.
Went through again, this time with two other people
- Demolished the boss.
- He stood still alot, despite being pounded on.
- Perhaps he should move more if he's getting hit alot in one position?
- More mobility = more life for him.
- Dropped a new gun, WAY different from the last, I like it!
