Old school manual was... hecking cool ! I love to see this kind of details.
The combat system is interesting. The use of dice kinda reminded me of Dicey Dungeon, even though they are using them in a different way than yours.
I think I didn't play enough to see all your work on the game, but I already think it has a great potential as becoming a really cool project !
My only gripe is that the full game is not totally in 64x64 (the character is not snapping to the grid, for example).
But that doesn't alter the experience at all.
So, count me in for future updates (if any) !
