I really enjoyed this game! I was able to find the six main tapes (along with some of the secret ones) and see Ending 1. Something about the lowpoly aesthetics and inherent mystery of the dream world really gripped me. This is a game I am going to ponder the symbolism of for a while. May even poke around again to get the other endings at some point.
I think my only big issue was that after I got the ending, the game asked me if I wanted to reset my progress. I pressed no, but it shut down and my progress was gone anyway ^_^" other than that, everything was very cool and solid. Good job!
