I liked the concept and the puzzles were nice.
I couldn't understand what the voice was saying. I wasn't quite able to pick up on what the voice was saying due to how low volume and distorted it is. But that's just me, who always turns subtitles on, and I don't blame you for not adding subtitles in a jam game! I just think that I probably missed out on some interesting story bits (maybe even hints) because of it.
I think that the tutorial could have been better explained: I didn't know you could pick up objects and so spent a lot of time on the second (I think) puzzle, where you have to do it for the first time. Maybe a prompt could come up whenever you face one of the cubes in grabbing distance to tell you "Press E to Hold"! A lot of games do that and it gets the job done, that way you wouldn't even have to do it in the tutorial!
In one of the levels I spawned outside of the play area. Was this intentional? I had to enter it again and then solve the puzzle to exit it... it was a bit strange willingly entering an area I will need to escape afterwards. I would either make the player spawn inside of the play area or maybe trick the player into wanting to go in. Maybe a big bright button and a sign saying "You win if you push this button" or something lol. But maybe the voice acting has more context that I wasn't able to understand.
Overall I enjoyed it. Well done!
