Hm, I'm not sure what the frame issues were. We weren't reading any null variables on our end. That said, one of us was on fairly old hardware and the other was on brand new hardware so testing was a bit weird. The character issues with the low settings are wild, it's definitely something we noticed happening but too last minute to really dive into how to fix it. I hope you were able to enjoy it despite that!
I wanted to add a win screen or something to make victory more obvious but I can confirm of your screenshot that you made it haha. We wanted to let you play past the ending so you could continue messing around with stuff so that's why we didn't have it cut to a win screen, but we should have made a pop-up window or something like that.
We'll have to look into more air control too. The jumps did seem a bit wonky at times so you are on to something there. Thanks for playing and all the feedback!
