Thanks for playing and the feedback! I'm very happy with your description, because this is what I was going for. :-P
The mouse was supposed to be held in the general direction in which you want to go, which I liked because it made things even more chaotic, but after all the feedback I guess it was too much. I DO have arrow controls but had no time to basically think how to say this to the player (low rez...) and I forgot to add the WASD key listeners. Will definitely add these after the jam.
Maybe I will make some kind of intro screen at each stage with the mechanic being introduced or some tip.
