Is it a bug that it always shows there's 1 more ball left than actually get dropped? For example, I drop one at a time, and then when it shows only 2 left, I drop 1 and that's it. If it shows 3 left (very last 3) and I choose to drop all, it drops only 2.
If there's a way to DM on Itch, I'm not finding it!
Here are screenshots instead. You can plainly see that when there are 2 balls left, the button says "ball", so clearly at a code-level, the game thinks there's only 1 left and then that's what happens, it drops only 1.

Also note that for some reason "Boring Guy" is up there in the top-left corner for some reason and it's there even when in other menus, like here:

I hope you find this helpful.
