Hope you fix it :)

Hey Vasileiadis, unfortunately I only had the time to write code that works in Chrome! I'll have a look later and see if it's something simple - I might be able to fix it, thanks for the heads up :)

Seems to work well enough (on Chrome), but I kind of wish there was a point to it. Shooting red spheres gets old quite quickly.

I honestly had a lot of fun playing this game. It's simplistic (all you do is shoot red balls, grab grey ones) but it does have a challenge, especially once you get to 100 or so seconds. Nice satisfying effects and gameplay, really. Good job!

Good graphics, good color scheme, nice particle effects! Fun game!

Fun! Highscore, ~120

Very good game! Everything fits nicely together. Good job!

Nice level generation! Physics were good. I'm not sure how the timer and scoring related.

Awesome graphics and feel !

Kinda forcing in the theme there :P
Anyways. I really like the visuals but I feel it lacking difficulty because the enemies are weak and dumb and that makes it kinda boring.

Even if simple, graphics are very good looking.
I spent some time playing before I realized I could use the mouse, and you know what ? I prefer the gameplay without mouse, trying to avoid reds. It's catchier, dynamic, our player movements are so much enjoyable that I'd rather move around than concentrate on firing at targets.

(and game seems maybe too simple / long with firing)

I think it would make a nice second concept.

Smooth scrolling/camera and nice gameplay. Cool!

Really liked the minimalist look. Also liked that you were able to fly by holding jump, shooting down and "jumping" off your projectiles! Sort of like a rudimentary rocket jump.

Very nice and smooth feeling game. Good work!

Very satisfying gameplay, there is a certain flow to the game. And I loved the effects. Overall great job - high scores from me on Overall and Fun, low on Theme. :P

Absolutely fantastic game, love the style, the colors, everything very responsive, just a great lot of fun to play!

Simple but really well made game. I like the colour scheme too!

Really like the procedural level! Perlin?

And how did you do the collision? I'm going to be looking at the sourcecode :)

I found I got trapped easily in sink-holes I couldn't get out of.

A really fun shooter with great physics. It wasn't clear how this related to the theme, aside from the timer counting in up increments of ten seconds. Regardless, I probably had the most fun with this game than any I've rated so far.

I didn't understand how my performance interacted with time interacted with my size -- more explicit in-game feedback would be great. This was a lot of fun!

Hectic! And fun :-)

I loved the dark shade against the yellow. It was pretty pleasing to the eye. I like the minimalistic art style.
But I'm not sure what the red bar at the top was for? Health?

Fantastic! Really god fun, although it didn't save my best score...

This was really fun, it got very hectic after about 150 seconds which I really liked. I'm not sure if this is intentional, but you can fly if you shoot below whilst jumping.

Really insanely fun and well done!! I featured it in my Ludum Dare 27 video compilation series, if you'd like to check it out, http://www.youtube.com/watch?v=MGdyZZ8iT10
