You can play on a touchpad, but you must be skilled and experienced with playing games on a touchpad :P
I play on a touchpad :D
This game is really cool - simple, but it is not easy. It provides increasing challenges and you have to think before you act, while even having some levels make you think on the fly, because if you wait - you die.
I give this a 10/10 & 5/5
Nice work :)
