A little late getting to this one. I'm a fan of procgen and I've seen an MVM entry attempt it in a previous jam, but they're much harder to critique. Since you're going to submit this to the SMVM, I'll just list what I think can be improved.
- Power-up descriptions and keybinds should be quickly understood. In my game, I really wanted to communicate this in regards to the player's goal and prevent walls of text in my controls menu. For the goals, I quickly explain what the goal is and show what the player is looking for. I feel like this would work well in your game.
- I know this is planned, but there should definitely be a map system . Not just for the player, but for you as well. I think this would be a cool way to quickly assess your generation rules and tweak things. You may already built a tool for this, but I just thought it would be something to add.
- Nevermind3476 is right about dedicated rooms. For me it wasn't the anticlimactic feeling, the placement felt odd.
- Sound was solid. Although, if you intend to more add sound and music, I would lower the volume of the jump.
Overall a cool entry and I'm definitely going to keep an eye out on how it improves. I really liked Missing Cats (I still think the player looks like Bobby Hill), so I have a feeling you can really improve this in the remaining time of SMVM.
