wow... this one got me hooked for the whole experience. really clever level design. I saw some Blue Prince/Superliminal/Viewfinder vibes, and I think those are really cool games that I respecto a lot. If that's the inspiration, congrats!!
Even when you can see they are simple levels (we could not expect more in 9 days I think), its obvious that it works really well, and they are well planned, (the fact that the camera points in the direction where you should put the thing is a very very good decission to keep us playing and not "wonder" around the room looking for "what am i supposed to do".
I think it's got potential to become a bigger game that evolves with 2 or 3 more mechanics. and watching what you did in 9 days, I'm sure you can make it even better.
The music also was a good choice I think, and the atmosphere you created was also in the good direction
I have only one issue, that is actually just a suggestion, and its also the same issue I have with blue prince actually xD and its the walking speed is toooo much slow for me, I think it's a bit more enjoyable when you can move a bit faster! but again, just a subjective comment!
good job!! (I will check your other games when the jam is over, I see you have loads of them!!!)
