Thanks, for the feedback :) Would have jumped in myself but I'm nowhere near a mouse till Saturday...
They are both on the list but got pushed back by other stuff that was more broken ;) I had to submit a little early so there's almost 20 hours left on the jam clock that didn't get used. Quite a hectic jam...
For the gravity I'll need to do some experiments though. I wanted the switch to be a little disorienting, with the switch being on landing you can somewhat choose your time and place by switching gravity during flight. But I'm pretty sure I've overdone that by now.
For orienting there is an icon in the bottom right that keeps track of gravity. I found it made orientation easyish with some practice but still kept it something you had to think about. So during the limited playtesting with other people it made for some nice, planned moves and some tense, recoverable screwups when things got stressful. I'll definitely try relative controls for gravity though.
Like multiplayer the gravity switching was an idea that was nice and simple as a short bullet point ;)
