Hello there, orbless rpg dev!
Very solid and bug free foundation there (at least for me). Visually coherent , simple and effective, although some sprites are placeholder art from the looks of it. Inactive monster for example seem to have a talking indicator, which probably symbolizes them being "asleep"? Anyway, that's not a big deal for a first demo.
The only technical thing i noticed was the mouse cursor. When starting up the game the cursor movement felt a bit off, like it was a bit sluggish.
Please develop this game further and give it a lot of cool stuff, im really rooting for Paco the baldy!
