Explore a fractured world and rescue the migs that once protected it. Craft or purchase weapons and tools to help in your journey to defeat the evil blomsters and free all of the migs!

"A crafting system designed for those who don't like crafting."

Don't like spending time gathering every single resources in the game? No problem! You can unlock all recipes and purchase any item in the crafting station using the money you earn from trading in minerals you've collected (some resource gathering still required).


  • Gather resources to craft weapons and tools.
  • Mine minerals to trade for money.
  • Process dirt and smelt minerals for a better monetary reward.
  • Find and rescue the migs who will become your companions.
  • Become one with your mig to solve puzzles, fight enemies, and reach otherwise unreachable areas.
  • Explore 4 unique biomes with their own uniquely generated mines.
  • Hats!
  • Gamepad and Keyboard support (gamepad recommended)

This free demo contains over an hour of gameplay. Because this is a demo, there are still pieces of the game missing and music is entirely placeholder. Right now there are 4 biomes, 1 boss, and 7 mig puzzles in the game. The goal is to expand on each of those numbers greatly for the final version of the game.

  • More biomes (ghost, zombie, etc.)
  • More boss fights - one per biome at least
  • More potions and buff effects to apply to items
  • More migs
  • Mig customization
