i think the idea was very good! Congrats on working on your first jam i hope you keep on making more games
Here's some critiques for your next time
- If you're working on a jam alone its a good thing to have a short scope that you can easily work from, and build your ideas from there (for example maybe starting with one roulette was better). Its easier to build on top of something well done than trying to grasp complex mechanics at the start!
When working on a game its better to have peers that can help you in areas you might not be proficient yet, but if you do want to learn all the ways of game making i sugest learning the fundamentals of each area one of a time!
Keep up the good work!
