oh lordy D: well I'm glad I got a little closer, thanks for all this testing!
Regarding being out of canvas in future games, letterboxing got put into the recent big release that should solve a lot of these problems with games going forward!
Thanks for playing! My guess regarding Thicketon has to do with a screen space problem, that seems to happen more often on Mac builds (where the exit is offscreen and can't be clicked). I'm chatting with some Mac developers to see if I can sort out this and the executable bit, as well as see if I can get a build that functions on Linux. Thanks so much for your patience! Exporting to Mac has been a learning process for this jam game =[
