Pretty good, especially for just a day. I would love some corny farm music and some SFX. Also, I think a little additional time planning out the upgrades so they feel a bit more impactful would be great. I really wanted damage/fire rate because the spawn rate was too high to outpace, but sometimes I got neither as options, and then the upgrades didn't feel too meaningful or like upgrades at all. But that is me being really picky for a game jam game especially if you built it in a day. I like the general control scheme - it felt good after taking a few minutes to get accustomed to.
