A side-view exploration platformer in a world drained to ink and paper. You are the Wick, a hooded lantern-bearer. Four colour cores are hidden in the Hollow; absorbing one lets you light that hue, and the lantern holds exactly one hue at a time. While Blue is lit, white veil walls become deep water you can swim up. While Red is lit, faint smoke becomes solid crimson platforms and spikes turn brittle so a dash shatters them. While Yellow is lit, chalk slabs become energy rails you grind along. While Green is lit, grid fences become climbable vines and fence tops become trampolines. Reach the Prism at the Summit carrying all four hues to win. Controls: A and D or the left and right arrows to run, swim and climb sideways; W or the up arrow to jump, swim up and climb up; S or the down arrow to swim down, climb down or drop off a rail; Space to jump and to leave a rail, vine or water; Shift to dash; number keys 1, 2, 3 and 4 to light Blue, Red, Yellow or Green, or to snuff the one already lit; Q and E to cycle the lit colour; you can also click the four lamps in the palette at the bottom of the screen. P pauses and resumes, M mutes, F toggles fullscreen, and Enter restarts after a loss or a win. Hearts show your remaining ink drops; spikes and enemy contact each cost one, and you respawn at the last lantern post.
