Just wanna leave a few bits of feedback, having recently played Classic Mode on the highest difficulty setting.
- Sometimes enemy AI can be... finnicky. Sometimes their own attacks lead them to kill themselves and not in the intended way, and other times they somehow end up in a stateloop of spamming their recovery (I found this, fighting Heavy as Little Guy). This isn't the same as when the AI is really smart and puts up way too good of a fight (fighting Manic as Manic, for instance).
- I get the idea of the Minesweeper stage. Putting aside its gimmick of the unpredictable bombs, which are equivalent to Danger Zones in Smash Bros., the real problem is the screen crunch. Since the stage and characters are zoomed out from the screen, even when playing in full screen, which naturally makes it harder to keep track of everything. I imagine this would be HELL to play on the game's smallest screen size. In fact, I can prove it, right here.
