Hey there's a free demo for those who haven't decide if he can manage full game yet - if you can cope the demo level - be sure you are ready to pass the whole game!
There are 3 level in demo - where you defeat a mini-boss, open double-jump ability and will die many time (as usual).
There are also new achievements in the main game - not hard but pleasant - achievements are always pleasant.
Have a fun and enjoy the challenge!
