Cool. I think the look and feel of the game. The pixel art is simple but works well. I believe you were going the procedural route, which is unique and I like the idea of replaying a game with different layouts.
Some thoughts:
- It's a little odd having some of the SFX hard panned left (menu selecting, dialogue, jumping, etc.). Especially true for the character being in the middle of the screen, and I'm hearing the jump to the left!
- I'm having trouble figuring out where to go, since it's not always clear where I can enter / what has collision has doesn't.
Good job!
