A very interesting puzzle game. I'll echo the other folks who say the ramp hits high at level 3, but I did appreciate how well everything is presented early so none of the mechanics are mysterious before you have to go about using them. I think my one bit of a suggestion is it should be a bit easier to tell when a panel is activate-able versus when its dead, since that's central to the puzzle solving. The sounds and visuals are tops! Thanks for sharing :D
