is the big slime guy the final boss? i can't get past him.
Skill issue
theres a boss every 10 levels but if ur having trouble with the first one... gl
i had trouble fighting him for a while but try moving lots to doge the slimeball and just set ur mouse on him and shoot while moving to dodge his attacks
Focus in the attack and crazy shots(sorry my english is a trash)
thats the first boss lol
