I bought Bananza and have played only about two hours. Zero framerate issue but my biggest problem is this game is just nonstop button mashing.
I hardly see what's happening because its just particles everywhere while smashing the same buttons over and over. Gets kinda repetitive really fast.
Maybe it will get less mashy but I'm not blown away so far. Mario Oddesy definitely blew me away pretty early, so when I saw that comparison and the same company made it I was really excited.
I don't feel like I’m exploring the world, I'm just destroying everything all the time. Hopefully it gets better- my kid likes it, maybe I'm just old and lame.
