I love those kind of games. This entry takes the 2D world and make it into a perspective discovering game. This was honestly pretty cool! It was sure tricky to solve the moving platform level, but with some thinking, I managed to complete the game!
It's also really cool that you managed what I would assume is a shader that shows only the intersections of the visible models in a week while doing the rest! It's probably not done by only changing the camera clipping planes to like 1 and 1.0001f, else the inside of the objects would not render.
I also found some extra platforms at the final level that go upward (by using the rotation feature.) Could climb to the top, but I have absolutely no idea if there's a hidden easter egg there.
Apart from that, awesome entry! Nice work!
If you've got some spare time, come try and rate mine! It's a fun multiple endings type of game!
