first of all, thanks for your feedback :)
Dimensional Instability is quite nice :) .. i liked your menu navigation. had kinda rough times on easy .. the first time, i stopped right where a barrier was before it switched back, then i had some issues, with the platforms and the spikes :D but after finishing it the first time, i did the normal level right away :) .. some jumping sound would have been nice, but who am i, to judge someone about missing sfx when my game has no sound at all :D
good job, liked your game :)
