Impressive work! I've got somewhat lost a few times, but managed to finish the game in the end.
I really enjoyed the atmosphere, both the opressive music and the overall vagueness of visuals/story. Character movement felt quite solid, and the tutorial part was very well done!
Feedback regarding rough edges:
- Respawn timer is very long? When I first died, I though the "dark water" just makes you invisible, because you were still alive and could keep moving for a few seconds. You can also "die" multiple times, thus extending respawn timer.
- The character could really use coyote time for the first jump. Without it, the second jump can act as coyote jump, which gives the impression that double-jump sometimes bugs out and stops working.
