Love the game concept, you can really see how this lead into The Other Side! I agree with Raging Fails that the physics are clunky and a little confusing. I didn't realize I had to press E to put things in at first. Really enjoyed playing through most of your games tonight, and I'm leaving a follow to see what you do next!
I noticed a bug, not sure if you wanna patch this or not, but I found that you can cut the money with the cutting drawer open. You can still pull the lever with it open and the money still gets cut if you "cut" it while the drawer is open.
