The game is intended to open in a 9x16 window, which is what happens for me when I run the build. There must be some scenario where it is still opening in 16x9, which sounds like it's causing a handful of issues related to visibility, etc.
You can juice all the fruit, even the big ones. Some are just more delicate and hard not to break on the gamepad (though it is doable if you're careful). Lots of rough edges here to figure out, thanks for playing! 😜
