Wow this is a quality game
I really liked it. It is not fast but takes some strategy. I played as shrewd and got up to the flame enemy and got stuck.
I do have some suggestions I think would make it better.
I think the upgrades should be a little cheaper, or give more xp points, epecially at the begining.
Maybe some varying difficulty levels.
A place to train against random weak opponents to get a little more xp.
Get rid of the level 6 attacks (are there any higher?) they just do too much damage at once.
The characters were pretty good but the backgrounds could use work. A static scene is fine but spice it up a little.
I was always out of magic, a tile that drained magic from the enemy just using stanima (or converted your stanima to magic) would be very powerful and helpful. Also a tile that does the opposite.
This was a fun game and I would definately play a longer adventure version.
