This is... a masterpiece. I truly enjoyed myself from beginning to end - I couldn't even bring myself to be sad it was over, the ending graphics and final scene were so cute!
I will note there was a minor bug with the Berserker Splash Axe skill, though - sometimes the second excess damage attack wouldn't trigger. I'm not entirely sure what causes this - I think most of the attacks it didn't trigger on were critical hits, so maybe a bug with the critical damage calculation...? It wasn't game breaking, just made battles last a few hits longer than they would have otherwise.
