This is a demo for the metroidvania Undercurrent. Please help out this project by sending us feedback. You can fill out a quick google survey, post to the discussions section below, or join the official Undercurrent Discord. Fare warning this game is difficult if you don't play a lot of platformer games, we wanted to test the scope of play in a very short amount of time. The demo will probably take 10-20 minutes your first time.

CONTROLS:

  • Arrow keys to move/look
  • Z to jump/wall jump
  • C to roll
  • X to attack (note: can't attack at beginning of demo)
  • A to heal

There is technically controller support but it has not been play-tested and therefore might not be useable. And, while we have provided a web version of the game it is highly recommended that you download the game for best results.
