This game is too hard for me :P
Looks like the platforms and spikes are placed totally randomly, which lead to sometimes the only platform I could jump to had a spike on it. Also, since the player is moving vertically, it would make sense for the screen to be portrait rather than landscape, just to give them a better view of the incoming platforms. This would also help keep the player onscreen as I jumped past the top often.
Though I must say I did liked the pixel art and animations :)
