Initial thoughts after a few levels of gameplay:
A solid puzzle platformer with interesting mechanics. Use a lantern to reveal the mysteries of level around you as you avoid spikes and solve switch puzzles. It has a distinct "Gunpoint"-esque feel to the art and ambiance.
The first levels teach the mechanics of the game without being obvious tutorials. A fun diversion and a great demonstration of what can be accomplished in terms of level design when you have a fun central mechanic.
Final missing start is mostly just an indication of my preference for action version puzzling.
I will be coming back to play more of this game.
