Your group created a mechanically fun and challenging game. The game design was on point, with organically teaching players new mechanics and helping them problem-solve with existing mechanics. Overall, a fun experience. I don't have much feedback to provide, as I can tell you and your team have put a considerable amount of effort into the game. The only thing I would add is the following:
- An active death counter would probably help make the game more engaging, as it could encourage "no-death" runs and allow for some bragging rights.
- Additional sound effects for deaths, door closing, and dialogue.
