Thanks for checking the game out <3
A few points tho...
I designed the levels knowing that it could be possible to soft lock (in some it's an intentional design choice). That's why I included an option to restart the level.
Also the difficulty of the level determines how much weight you put on the other side of the scales. If you only do easy you won't be putting much weight on and you'll probably not be able to balance.
And the error is known by me. It's cuz I keep using the quit() function which seems to work when I'm coding but not in exe form... Oops..
