Binding of Isaac creator Edmund McMillen has released the first gameplay trailer for his upcoming turn-based puzzle RPG (and Isaac prequel), The Legend of Bum-bo.

First announced back in 2016, The Legend of Bum-bo pits the titular lead character against "hordes of paper goons", according to McMillen's latest blog post. Victory means more coins, which can be gambled away at casinos.

Bum-bo's assailants can be found throughout the game's dungeons, which "much like Isaac", are randomly-generated to provide an always unpredictable mix of monsters, bosses, traps, puzzles, and spells. The latter can "range from jagging stuff with a fish hook to summoning mom's leg to crush all who stand in your path", says McMillen. 

Combat comes in the form of a match-4-style puzzle system, where Bum-bo produces pagan glyphs from his bag of trash, then lines them up to create offensive and defensive attacks, and to gain specific types of mana for spell-casting. You'll find some of this in the teaser trailer above.

McMillen says that The Legend of Bum-bo is "nearing the end of development", and that the game will launch on PC and iOS later this year. A Switch version is planned for release in 2019.

McMillen is also working on his recently revived "cat lady simulator" Mew-Genics, which still sounds like it's at least a couple of years away from completion.
