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!
