Nice submission! It's really hard to get a good game going in such a short amount of time!
This looks mostly like it's a Roulette table...? I don't see how the Plants vs Zombie defense mechanism really works to stop the dice from going across the screen. And the spinning mechanism doesn't seem to produce more money after it completes like I'd expect a Roulette table to play. I put all the money on all the things, and it never increased after completing a round. So I'm not sure how well it works with the defense part.
I also game overed, I think? I had $1000 moneys, and I just suddenly went back to the beginning screen.
The graphics are actually pretty good! And I did not encounter the bug you mentioned in your comment.
If you were to continue with the concept, add some way to communicate how the game plays, and what the goal is!
