This reminds me of those moments when you let a little kid win on purpose so they don't get upset xD Such a creative idea. Intentionally trying to lose money at a casino is a really funny twist. My favorite part was when my luck got really high and I had to place the smallest bet possible on purpose xD
I also really liked the artifacts. They do a great job helping you get rid of money. After hitting a huge jackpot, getting an item that immediately takes a chunk of it away felt surprisingly satisfying. They actually helped me win a couple of runs.
I also want to mention the art. It fits the game's vibe perfectly. It's goofy and doesn't take itself too seriously, just like the whole situation the main character ends up in.
The only thing I felt was missing was a bit more variety in the strategy. It seemed like the best option was almost always to put the biggest bet on a single number, except when your luck got really high. But I totally understand that it's hard to add more depth during a jam.
Other than that, this is a really fun interpretation of the theme, and I had a great time playing it. Great work!
