This game is pretty fun, the physics are good and the environment models are well made. The AI is my favorite. When the worms hit you, you don't die automatically. You get thrown around until you take too much damage and get destroyed. I really enjoy that mechanic.
The good:
1. AI and attacking
2. Driving physics
3. Environment models
4. Car models
5. The jumps and obstacles are fun
6. The red ball powerup is a life saver!
7. The worms increase difficult at a good pace, and the red worms are fast which add more of a challenge
The bad:
1. I wish the missions would vary instead of collecting the same item
2. Needs more obstacles to jump to grab items
3. The buttons at the bottom (the 2 red ones) were confusing at first since I thought both of them were either single boost or double boost. Maybe adding in a symbol or changing the color of the red ball powerup?
4. The ads feel like they were just thrown in there, instead of giving the player a good reason to watch them (earning an extra boost or double red ball powerup, something like that)
Overall this is a very well made game and enjoyed playing it! I hope you continue to update it and add more levels.
