Liked the concept, of powers getting switched after countdown, also loved your take on invisibility, if no one can see you then you also can't see anything lol. First I thought ok shift can be used to pull and push box, great, then next time I pressed shift everything went black, then I noticed, oh powers keeps rotating after timeout.
Also I noticed times getting speed up, when using more and more, that is also nice as it will make player use it more wisely. In push and pull multiplier works normally, but in invisibility UI display for multiplier gets stuck at 2x although time does go fast and fast as more is used.
There were few camera issues and although I can move up and down, with arrows, I couldn't wall climb with arrows, W key worked but up didn't.
Great game and concept though.
