It's on the web version, and it reproduced every time I've tried.
That would explain it.
The code for the downloadable version is the exact same as the code for the web version.
I assumed that it would work the same, but it turns out that a lot of changes need to be made when porting between the two.
Sorry about all the trouble. If you try the downloadable version, the problem shouldn't be there.
(also the second level on the game jam version is bugged, so you wouldn't have been able to beat the game anyways)
I appreciate you playing my game and providing feedback, though!
