Woah, nice! Definitely the most effort put into a game this jam. At least so far that I've played.
Nice atmosphere and theme well implemented. Nice use of thoses Synty assets as well. Aiming in the throwing puzzle was super hard (couldn't get the last one for the longest time) and It wasn't as obvious where to reset the game.
I kind of got stuck in 3B. Couldn't figure out what to do to make it stop looping to the same room. There were some interesting glitches also. Some doors melded into portals and disappeared when approached... Couldn't tell if it was by design or just some random glitch. :D Also, it seems I never made it out, since there was a screenshot of a "stats" screen I never reached.
