Neat game. It took a few seconds to realise that the settings were swapped and you had to change Left and Right but after that it worked pretty well. I managed to get to the level were the spikes close in on you at which point I rage quitted after the 50th time :D
But I guess it tells something that I managed to make it till this point and tried it 50 times. A little tutorial would have been nice but since there weren't lots of mechanics also not really necessary. The low contrast was already mentioned and apart from that I would only say that it is a small but neatly put together game. Congrats! :)
