Wiped my post, just got the part where you can select a stage. And it plays well as far as I can tell. The momentum took a little while to get used to, but seems great on vita, haven't played other versions though.
Really enjoying the game, worth the GB of memory space, think it's staying for good on the main card.
You know those yellow things that fly off some defeated enemies sometimes that change into something uncollectable(?) for a few seconds before disappearing.
If I wasn't able to collect it before landing I'd timeout and try and catch it.
Can you get it while it has the red outline somehow? Or is that just a visual thing and it's locked once it touches the floor?
