A solid entry into the jam! I really liked how you incorporated the various challenges into your game.
Polish/Completeness
The game loop works, and I did not encounter the bug you listed on your page.
Although short, I like that you added music to the game. I would have liked to see some included sound effects as well.
All the cards have artwork, as well as the background and UI.
I would have liked to see some card animations.
I want to give it a 3.5, and I could push it to a 4. But to be fair to the people that I've already rated, I'm going to round down to a 3.
3/5
Creativity
The game is pretty basic; it's a plus or minus game.
I like the addition of a timer. I also like that you followed the jam's ingredient guideline of adding a "ruin".
4/5
Fun / Engagement
For me, the depth of the game revolved around clicking the smallest numbers and hoping I won.
3/5
Overall
Awesome work completing and submitting a game to this jam! I really liked that you followed the theme of the game jam. A little more depth in the game mechanics, and a tiny little bit more polish, and it would be 4s across the board!
Keep up the good work! And keep making games!
