Good timing, as I just put the finishing touches on this month's devlog:

Basically, my rhythm-based roguelike on original NES now has a proper economy, with gold gain and shops to spend the gold in. It also now supports PAL and Dendy systems, which is especially wonky due to the different framerate, but helped a bit by this being a rhythm game. As long as the music plays at the correct tempo, the rest of the game adapts its speed and "feels" correct at the lower framerate.

Tons of work left to do, most of it pixel art (I'm learning as I go) but it's progressing quite nicely.
