The game is ok.
You can double jump and hug walls in Super Meat Boy fashion.
You can shoot too.
The springs are kinda clumsy.
In any case there are several levels you have to find by yourself, to play on :)
The default keyboard control keys are not very well placed in my opinion, and you cant change it ingame.

It seems that you cant change graphic settings or switch to window mode either.
Also i think the game may be lagging after playing for a while, maybe depending on the level.
I think the game would be nicer if it had a bit more polish to it, but anyway its an ok platformer.
