First of all, great game. I really like the concept, graphics are nice and music is cool. But I think some things need tweaking. The "orange water", for example, is really hard to see because of the background color scheme. Next, switches. They need to be more explicit. I only discovered they were switches upon landing on them by mistake. Finally, the physics feels a bit off, gravity is weird. Other than that, it's a cool game. 4/5
Would be much better with a custom player sprite and better graphics. Right now you took the sprite from Flixel's FlxCollision demo... Anyway, Cool concept.
