Hello, and thank you so much for playing, glad you enjoyed it! ^^
I'm happy to get some constructive feedback from you \(ϋ)/ Lots of fair points. This was my first game (not counting tutorials) and this will be very valuable for future games.
About Dedal's area: it's actually the last area of the game, so you didn't miss much (assuming you saw the last custcene in the maze). I had to cut the scope back then, so it might not have been communicated well in the game that it was heading to an ending once you get out.
EDIT: Just saw the stream, the exit was in the same room where the last cutscene could be seen, directly to the left. Perhaps it wasn't too obvious that the corridor goes up as it did lack any indicators.
