So not only is Relic Hunters Zero a really awesome game you should check out but the team creating it Rogue Snail has also released the source code and github repository! Devs helping devs is something that always gets me excited! In this consumer based game we play called life it is so refreshing to see people not just willing to help here and there but straight out show everyone how they did it.
One of my favorite things about this game is the different classes. You can smash your way through all the levels with a melee class or play your keytar gun to victory!
