A prototype for JamCraft4. Use your alchemical machinery to mix colourful essences and deliver orders!

Mouse to move, left mouse click to pick up or drop items, and right click to activate machines. Mix essences in the RGB colour space, guided by your colour map, and try to get a high score!

Planned features:

  • More interactables such as transmuters, purifiers, randomisers.
  • Naturally-spawning items such as gems, plants, etc to use in your combinations.
  • Unlockables and multi-essence orders.

P.S.: If it runs poorly in the browser, just download the version for your platform down below!
