Nice job. I'm assuming this was inspired by Crypt of the Necrodancer? It even has a similar looking "bounce" motion when the main player moves.

Aye, the inspiration is not subtle. Technically it is the latest entry in the "rhythm-based roguelike" genre... which to my knowledge mostly includes CotN and its sequel, Cadence of Hyrule. Both are excellent, and I recommend them highly. Of course I'm unaffiliated, so this is more of a spiritual successor (... demake?) and is its own thing in terms of IP.
