Honestly the minigames wasn't really the problem itself, it was the bugs and the implementation.
Probably shouldn't be on the save every time, like the first time is funny, the rest of the times im failing it im just staying still waiting to be able to try again.
On the bosses themselves i don't see why not, you don't stand still, you have to dodge the boss and do stuff.
Maybe let it last one second longer so it's not as easy to fail.
