There are oly 2 buttos i the game:
- Spaw — You produce the 1st mob, which will brig moey as log as it is alive. However, you caot create more mobs if you have reached the limit.
- Improve - Improvig mobs leads to a rise i the price of Spaw, but i retur you get eve more profit

They give money for the destruction of mobs, but who will wait for their spawn time if you can make an automated farm? That's right, nobody! So you have created a farm where mobs spawn, they die, and you make a profit. You don't even need to dirty your hands, you just need to spawn mobs, relax and watch the automated process.
