this game is slick as heck!
The shifting has an awesome visual effect. The puzzles that you created using it were pretty clever. It took some levels before I fully understood how your game wanted me to think about it, but once there I think it was really satisfying figuring out puzzles. The best aha! moment was level 7 and realizing I had to look for ways to position myself on the foreground with the blue blocks in the background.
The hardest bits for me to grasp at first was that when I moved, that also moved the glowy bits out of the way too, so I didn't interact with the mechanic as much. At level 7 is when I fully grasped how your puzzle mechanics ought to be thought about.
Really clever stuff! It is genuinely impressive how you guys managed to make 10 levels in this time with this amount of slickness. There were hardly any times that I got stuck or frustrated, any time I did it was mostly because I had placed a block wrong mid-air and couldn't reclaim it.
Fantastic presentation as well! The 3D perspective looks great and the blocks made it easy to gauge how high/far I could actually jump.
