The slightly long gumball machine time is mostly used to rest between bosses and quite often to let a heart appear if you run out of life. But I might consider a “skip transition” button. I'll make a note of the idea (right now I need to rest :D).
I've updated the game with a “skip” button. This should allow you to skip the boss choice scene with the gumball machine (for the record, in the game's built-in speedrun mode, the timer pauses during boss transitions, so using the “skip” button won't affect the time count).
