Red Sting Boss

a new boss appears in Isaac, from street fighter 2010 here's red sting, the flying scorpion, you can find it at caves and catacombs.

UPDATE: there's a modpack containing all of my bosses now, check it here: https://psteamcommunity.yuanyoumao.com/sharedfiles/filedetails/?id=3033270977

it has it's own music from the original game (you can disable it if you don't want with the mod config menu pure)

requires custom stage api to work
