This game is pretty great so far. Actually haven't touched Adventure mode, went into Online pretty quickly after trying all the modes.
The ranked play is weird with how it randomly cycles through game modes, I like variety at least. Almost no one is hosting free play rooms which is weird considering it's release day?
I don't really understand Big Bang mode, with Tetris it just seems brain dead easy and all about who can input the fastest, and that seems like it's mostly decided from the get go, so if you're near the same skill level it just goes on forever. I do alright with it in other modes, but Puyo Puyo is way less obvious to me to pick out the chains so it's futile to fight even a basic Tetris player there.
I want to like Fusion mode, but every match I play seems to drag out forever. It takes me ages to set up a nice combo half because of the mind-bending where I dunno what I should focus on, and half the piece distribution feeling like it never gives what I want, and then when I have an empty field it takes forever to start up again. And most players don't seem to be any good with it either so it goes slowww.
