Karst is a 3D first-person puzzle game set in a cave. The premise: you fell in, and you need to find a way out. The mechanic: this cave is home to a series of unusual crystals, each of which seems to have its own unique effect. If you’re clever, you can use these crystals to progress through the caves – if you’re not, you’d best get used to not eating.
A section from the level we're working on right now. You'll see the dampener (blue) being used to dampen the death crystal (purple). As the player takes damage, they go back to the health crystal (yellow), recovers, then walks past the now-dampened death crystal.
