One of the most polished entry i tried.
Music and art are incredible. The gameplay is well tought and clear. No guessing, you know what to do almost every time (maybe a little signal that explain you to go to the right, over the first power download, it would have been clearer, i admit i lost my self in that point). It's a great platformer. loved the strategic use of the power mechanic.
Well done!
Ps. A technical question, cause i'll want to do a similar thing: For the conveyors you use the SurfaceEffectors2D?
