Thanks for trying it out Loubi, it's definitely a game for nerds! I've thought about how it could be made more accessible, and even how it could casually teach people about microarchitecture, but I haven't had any ideas at all about how to make it less nerdy :D
Audio was on my "to-do" list for the jam but I ran out of time. I have code lying around to play sounds which I could have used, but I don't have much in the way of sound effects and music to hand, just some fantasy RPG stuff which wouldn't have fit the theme at all.
