Woah, thanks for the detailed response. Yeah I'll make sure to be thorough with dashing mechanics next time. I'm so used to platformer that it's natural whenever a dash exists you can dash in 8 directions. I'll also make sure to have a save system next time I do a Jam.
As for the bug you've encountered it's likely some integration error with the music plugin I'm using. If you can tell me what you did right before getting kicked out it'll help a lot in identifying what's wrong. As it stands error logs of a compiled version of the game can't tell me much.
