A good starting point for a combat system game.
The game fits the resolution very nicely and animations and graphics are great too !
The combats mechanics is interesting, I spent a bit of time trying the several bosses (A bit sad poison just last for a turn).
A good thing to add in order to avoid the "run and chase" could be the destruction of some part of the arena restricting players movements.
Or add an ability to drop a trap that last for 2 turns ? =D
Good job overall, would have been really nice with some music & sfx ;)
