I guess it's a bit of a love letter to that and Portal, isn't it? It looked a lot more Portal, until I added the dingbat gliphs to show which plane you're looking at, and decided to try out the Unity cel shading package.
Lol. Portal is a great game, and a good inspiration for this Game Jam too.
Also, the end results you got are really nice. I also liked the camera transitions and mechanics in general
(and I know, for sure, how dificult it can be to program good mechanics and recreate - or add - a nice Visual Style, all in only 10 days).
Congratulations.
