MidBoss is a video game about possessing your defeated enemies in order to become stronger. You play the weakest of the dungeon denizens, an imp with no ability other than possessing other creatures. Your goal is to defeat and possess increasingly stronger creatures, unlocking their abilities for yourself and becoming stronger as you go along, and eventually defeat and become the dungeon's ultimate endboss.

  • Quick Play mode for shorter, more condensed play sessions.
  • Custom Game mode that allows you to play the game the way you want to.

  • Cratefish as a currency!
  • Traps as well as unidentified and cursed items.
  • Trade with and sell unwanted items to a mysterious merchant.

  • Miss the good old days? Got some nostalgia for those eye-bleeding CGA cyans and magentas? Miss the old Gameboy days, or were you more of a C64 fan? There's 12 retro mode filters available in the options menu, and more coming in the future!
