The actual idea of the game is great, but the moving system is total bullocks!
I mean, you drift way too much and of course, the platforms are to close to the ground and considering that you jump higher than the height of the game, you should add more platforms.
I think also the traps are very easy to get into, first... spikes? on the walls? when you slide it is almost impossible to miss the spikes.
You need to work on this, defiantly, first with the physics of the movement and jumping, then add more platforms, OR just make the stickman smaller.
seriously, take my advise into consideration.
