I come back after more playtesting
One thing, which bothered me
I don't think there is any UI indicator telling players attacks take up 2 skill slots.
Some victories:
The Easy difficulty is as easy at it should be, but the Normal seems quite hard. Also the ogre boss really forces players to go into multiple attacks and stuns, preferable stuns.
Here are my win rates:
I lost way too many runs on Normal, so I played more Easy for testing.
