Having 3 bosses randomly appear in the early 3rd wave out of 10 waves is just impossible~🤣 Is this the limit for free-to-play players?

I thought the enemies got way stronger and couldn't progress, but I got a weapon called the Ice Spike Gun and tried it out. It has a slowing effect that makes the boss almost unable to move, so it's pretty strong! 😆

Recommended if you like games where you stomp zombies. Cleared up to Stage 6 without spending any money 😊 Enemies are getting tougher, so it might get difficult soon...?
