This game is pretty enjoyable and highly recommended for strategic gamblers. I got to level 7 wieee. The visual and music are great. Using your faces for the enemies is really cute and funny. The graphics is very unique as it really gives an inside the television vibes. It's very creative and adheres to the theme. I could see that we could employ some safe strategy like distribute the pins for safe playstyle, or go all in by making them adjacent to each other.
The only thing that I think affected the enjoyability of the game is, first, the bug where you can still spin the wheel while your enemy is still attacking. It happens often that I spin the wheel without pins attached therefore giving the entire turn to my enemy. Second, I think the gameplay is too long like each level would take a very long time to finish. Unless someone has hit a jackpot or has two red pins, it would go on for like forever I think. I've noticed that my defense could be stacked until thousand which is a concern on the balance of the game. But for now, I think a speed up button would be a good addition to the game as the spin animation is too long for me.
Overall, with a little more tweak, I would totally download this game and recommend it to others. And, this as your very first game jam, I'm really amazed with your output. Congratulations!
