It's a shameless Castlevania rip-off. But I've put the project on hold for the time being; I was going through some old files and thought that I should share some of my work in case I never get around to finishing it.
This looks really good, you did a nice job with the tilesets.
What is the game you're working on?
I really like the purple brick column at the bottom right: the lighting and feeling of volume and roundness is very refined. The stairs are full on castlevania which I've never really liked because they read at an awkward angle to the rest of the graphics, but it seemsto me you do make them cleaner to read than the original, which is a nice improvement.
I really like the human sprite also, the tenchcoat and hat feel a tiny bit bloodborne-ish, which is a good thing. The skeleton however could use a neck and a more menacing pose.
The purple background is awesome and feels much tighter than the foreground.
