AMAZING! I am currently building one (no where near as pretty, very much old school) for the c64. I am so impressed by what I can see. Do you have a devlog, or something about how you went about doing it, and the decisions you made?
I actually started this game with the ASCII art of a typical old school - that's what i grew up with and i still have a soft spot for it! I'd love to see your project - there have been some nice roguelike projects on C64 lately. As for a devlog, i may just write up a summary of how i approached some of the typical roguelike challenges on the C64. I'm actually hard at work on my next game so i might keep notes as i go this time!
