Okay, so here is a few suggestions I'd like to make. When opening an upgrade menu, maybe just have it swap over to a whole new screen instead of making it a pop-up screen that you have to scroll around in to find the upgrade you want. Also, the copper unlock is incorrect on the UI screen. I was well past the amount it said and it wouldn't unlock until after I had uranium and others unlocked, so you might want to double check the number for that. Also, the image of the item being crushed should have a cap on how big it can get. Other than that, the game has a lot of potential.
