This was really nice, I loved the low numbers combat and the way you purchase skills with EXP, I cleared both ruins and will go into the forest tomorrow, but I have some criticism:
I understand enemies are like puzzles the way you have to combo and then unleash the stored combo, very nice mechanic, but I feel the rewards are a bit unbalanced, I think crows are the hardest enemy yet they reward less than gnomes, which I can just destroy without even having to use combos. I would give crows a 50% chance to waste their turn so it's not a constant HP drain, or decrease their defense a bit.
Also I feel you can just cheese combat by escaping, I never failed to flee, and with the enemy being erased you can clear a dungeon by just fleeing.
Hope it helps!
