Hey, glad to hear you liked it. I love game manuals! I still have my Lords of Magic manual sitting somewhere; it's like 100 pages and heavy enough to hold a door open. As for the pixel-perfect stuff, I did indeed miss some details, but next year my goal is to get that hammered down first, instead of running out of time to do it. And yes, at some point I will be developing Micro RPG into a fuller game experience.
If you like the combat system, check out One Deck Dungeon by Chris Cieslik (published by Asmadi Games). My combat mechanics are based on his excellent game.
