The puzzles are interesting when you figure out the main mechanic! It needs a clearer tutorial though, I didn't realize what it was until I read the comment. The sort-of tutorial in the beginning made me think I just needed to stand at the right spot and then run.
The mood and the environments are well made, has a mysterious feel to it. There could be more variety in the environments though, not just yellow bricks.
Some more variety in sound effects would've been good, too - every rotating object seemed to have the same sound effect. Some sounds kept playing close to the player after you re-entered the "hub area", which was odd. There could have been more ambience and music.
Couldn't figure out what to do with the quickly rotating dog/panther. I noticed what made it stop, and what made it start opening the door, but was stumped.
It's an interesting and well-made game though, clearly you guys put effort into it, and it's great that you made all the assets yourself. Good job!
