I like the implementation of the lights to shut off one side of the screen at a time and the sprite for the scarecrow is quite cute! 

Very cool use of the limitation, but I also was struggling a bit with the laggy mouse controls.

I tried but I couldn't figure out how to even play the game properly 😭 when I managed to fill a glass it disappeared and afterward I couldn't get the machine to work at all.. Also it seems the mouse has latency but idk if that's intentional or not so I kept it out of my rating criterias.  I really like the idea of the two halves changing when you look at the other it's a really cool way to use the limitation

This is a neat idea splitting the screen, took me a second to get a hang of it, but the few small twists you added with things moving around made it interesting - nice job!
