You can tell this is by the Guacamelee team from the art style - and it has just as much character and attention to detail as those games. NSTW is an action RPG, but has a huge focus on unlocking abilities and characters throughout the game. You play as someone who finds a wand with the power to transform you into one of 17 different forms. Each form comes with a passive ability, and 2-3 unlockable active abilities that you can then use on ANY of the other forms. It allows you to create very diverse character builds. These forms level up by completing form-specific quests, which also teach you how to use the abilities well together and give you ideas.
