Hey it's a pretty neat game - using visual effects make the game look great, it looks better in game than in the pictures.
A suggestion I'd like to make is 1) configurable controls 2) make it so there's a small delay available to jump. Many times I've tried jumping, but apparently I jumped too late 3) for wall jumping, sometimes the majority of the body touches the wall, but not the feet, and because of it the wall jump doesn't work
I like your game it's pretty original.
There exists configurable controls! I can't change the game anymore because I dont have the source code anymore. :( its a old game from me.
