Very fun, and very good for a first pygame game! It kind of reminds me of one of those idle phone games I used to play a lot of. Very polished and graphically appealing, and runs well, even with a lot of beans on screen. I do feel like the game would be improved with some kind of obstacle system though, since once you've picked up a couple upgrades you're basically unstoppable.
Can't say I didn't enjoy the chaos that comes from trying to get your jump ability to level 10, though.
