Played till the end. Not bad a mystery solving game :)
I think some of the audio choices you guys made are not very good. In particular, when you reset the loop there's a high-pitch drawn out noise that I think it's pretty bad.
I like the different visual effects you guys have made for the game, like the god rays and the particles etc. However, I also do think that the visual style of the game is not very coherent. I understand it's a small team in a very short time, but making assets seem fitting together is something that a dev (not necessarily an artist) can get better at.
On the gameplay side, I really like it. I like the fact that you have the clues visible right on the UI, so I don't have to memorize them or flipping through menus. The last part where you find the last digit clue for the last room is a bit buggy though, the way you made it you can easily end up in an actual loop of just the 2 rooms (don't know if that's intended but definitely fitting for the game).
Overall, I think it's a good core, just need a visual and audio checkup and you got a good game on your hand!
