Nice game, I really like the music and the differnt level ups, but for me a bit too hard (i can't even win the first battle) and it would be nice, if you get level ups earlier.
Yeah it's a hard talent for sure to have the balancing so that everyone can enjoy it and beat it, something for my future games to focus on that balancing would be more fair to everyone (or atleast the player group who are most interested in the product).
