The custom battlers were really cool, and I like how smooth the animations were (OldHar's katana draw in particular stood out)! The only minor issues I had were with the map (although it was really nice to look at, it also made it a bit easy to unintentionally hit dead ends), and the balance of the last boss (I felt like I only managed to beat it through luck, although this might be intentional since it is the last boss). Keep up the good work!
