Rated. Placeholder graphics aside, i thought this was really good. I had some issues where the player character kept getting stuck on geometry, a swift press of jump soon resolved that. I liked the idea of the fake walls/traps, I think a visual cue for the cooldown of the 'reveal tool' would have been really helpful as in some places I wasn't sure I had pressed it or not. And what is the black shadow following the player, some kind of other gameplay mechanic you had in mind?
