I like the concept of the game a lot, it's very creative! I remember seeing your game's progress on the Discord channel as well. I'm pretty bad at it so I only made it 5 files deep on my first run, but the effects and polish is really nice! I also really feel the stress as I struggle for a long time on a bucket.
One minor issue I ran into is about picking up numbers. The hitboxes for it seems to be quite large, and I would pick up two numbers at the same time unintentionally which made me had to discard a group of numbers that I already found. I need to be quite precise in my mouse movements to make sure not to pick up other numbers. But it was still satisfying to find large group of numbers bunched up together and pick them all at once.
