later in the game when you don't need money the bat gangs become more of an obstacle. when you're doing great combos with regular batcritters you randomly hit a bat gang which takes you to an area filled with diamonds that makes everything go away so you'll eventually end up bouncing on the ground and losing your speed
It takes unbelievable amount of grinding to beat this game. You'll end up farming fish just to spam your stats until you're unbeatable. Not to mention the jumping and the lag. 3/5 for the potential
While the game is pause you can take your time and use a spell. When you unpause the game the spell will do its job. This is effective when you want to strike the base without leaving your minions for dead.
