1. The soccer is the dead enemies you grab and throw into the nets, it gives many points and the multiplier helps a lot after you killed a lot of them.
2. Recycling is the same thing.
3. I am not sure what you mean by sluggish, enemies do spawn fast, but you have explosive barrels to throw at hordes of them and you can also click the barrels and they explode in 1 second.
4.You are supposed to run when you are low on hp, and find heals. The soccer ball is the enemy. The jam theme said, "anything related to soccer, get creative."
5. Thanks for the feedback 👍
