I like the idea of this! It's a pretty interesting take on the incremental game genre, since you're using the currency you generate while spinning to send tornados to the city, and that's the way you get money (instead of the way most of these games would go, where just the spinning alone would give you money). It's definitely something that would be worth exploring further in my opinion!
Since I read your comment about the game being unfinished, I believe the only critique I could really give you is regarding time management. It's certainly something easier said than done, and in my own group for the gamejam we could've done better on that department (only reason we have most of the game is due to a few people doing a lot of time crunching lol), but what I learned from my experience is that getting the most important basic mechanics should come before literally anything else.
Good luck on future projects, and congrats for finishing the gamejam, even if you consider the game unfinished I still say it's a success!
