I think this game might be broken, every few fights I win the results screen doesn't load, it just hangs there, I wonder if it could have anything to do with me purposely losing the second fight with goons to see the ending for that area?
Update: It doesn't, I think it has to do with the difficulty you select, Simple mode seems to be having issues?
Update 2: Found a solution, spam the F4 key seems to get out of the blank Battle spoils screen.
