Thanks, I'm glad you enjoyed it, and thanks for the feedback.
For my next project I'm definitely going to add SFX as I add features so that I don't push them off til last minute and then ultimately not do them at all. I really like the tumbler puzzle in concept (changing the path you can take through a dungeon), but if I ever use it again I'll probably separate the tumblers out so it's not just four clustered together, that's a bit too hard to build a mental map around (especially without an in-game map). Speaking of, there is a map you can eventually find, but it's hand drawn and not super helpful, designing a map system is something I'll also prioritize for Metroidvania Month 15.
Again thanks for playing - I'll give Domino a shot later this afternoon, looking forward to it!
