Arsonist Heaven

This is the first boss, and you can absolutely cheese him. Get the weapon powerup and drop down, moving to the left or right and up to one of the platforms. The boss won't attack you when you are here, so drop down (+), attach him quickly with , then jump back up with and then again quickly, Wait for your jetpack fuel to get about half way then repeat until he is dead.

even easier way just pick up the gun drop down then go straight to the boss stay up close but jump from side to side so from his left side then shoot him then jump to his right side then shoot him just rinse repeat if you run low on health or fuel for the gun just go to the little shelves one on each side to restock up. I think he hit me once from this method don't be scared of staying close to him only his arm does the damage .
