So what I have noticed so far. In 2560 x 1440 it bleeds out past the right edge in both full and windowed. When you finish a gauntlet run and start another sometimes it gives the new character 4 energy, you can proceed to the end of the fight and it will hang, you can hit the cog and exit to desktop though. The solider as far as I can tell has no way to mitigate the high incoming damage in the second half of gauntlet.
Still enjoying the game a lot!
