Monster Boy is a whole new game by our friends at Game Atelier / FDG Entertainment, released shortly after our Dragon's Trap. It has been designed in cooperation and includes elements from other Wonder Boy games (such as everyone's favorite pig becoming playable!). This is an ambitious modern take and love letter to the open-world Wonder Boy genre, with large levels, puzzles, playable characters and everything you'd imagine if the Wonder Boy series carried to the 32-bits era with nice 2D graphics!

Wonder Boy Returns Remix is a remake of the original and first Wonder Boy Arcade title, which eventually got features on countless platforms back in the days. Unlike later title with pivoted the series into its action-adventure-rpg blend, this is an old school arcade game involving riding a skateboard, throwing hammers at skate, grabbing fruits and finding secret dolls. A classic well revisited and re-imagined by CFK.

Hope you'll enjoy them!

And in case you didn't hear what Lizardcube and Dotemu was up to after Wonder Boy: The Dragon's Trap, we released Streets of Rage 4 last year, and this year an ambitious DLC "Mr. X Nightmare" this year with a really fun and interesting rogue-lite survival mode:
