Cute little game! ..that took a lot of my time :)
I enjoy the idea of a 3D idle / clicker game, especially since you can make the way of gaining more points more involved than traditional 2D clickers. I feel like this one almost captures a similar feel to Katamari Damacy, in that you continuously keep getting bigger things. I think it would be beneficial to lean more into that, and let the player start taking down some truly giant things, like buildings and mountains.
The scaling at the beginning was absurdly slow, I get that it makes for a larger payoff later, but for a jam game people usually don't have / want to spend a ton of time on a singular game.
I think the flood idea can also work well if you designed more around it, other than just having it be a simple timer. If you had a larger map, you could incorporate areas that require you to get there in time, or learn secret paths to get to different places sooner. But, if you made these changes, I think the punishment for getting caught in the flood should be different. Maybe just ending the day, but not losing all of your things? Or causing what you have to count down, and not completely empty. Since you don't want players to avoid taking all risks because they don't want to lose progress.
Having different maps would also be a simple way to add more, just getting new things to destroy would be a fun way to add more replay ability. And you could also work in some unique mechanics to each map.
The fantasy of progression in this game is very good, since it is fun to imagine clearing out entire hordes of objects effortlessly, and thus gives a drive to want to be there. Although, I do think that the storage upgrade held this back the most, since it scaled by a static +2000, when I could easily fill that every time.
There are likely also a lot of other upgrades that could be explored, like maybe some that let you deal more damage to specific object types. Or changing the size of what you shoot.
Nice job!
