Narrative-driven concept, solid puzzle game with very understandable learn-by-yourself rules/tutorial and smart level design.
- Puzzles are very well paced and brings the player into the game. The game also plays very smoothly, movement feels tight and responsive and controls like a dream.
- As some others have stated out, audio feels really lacking. Just wished that there was even some simple music in the game.
I've never really been a fan of theme as a purely narrative device, so if you allow me to be straight, that deducts some points from me. But moving that aside, the puzzle gameplay is real solid - your biggest standout is how you design the levels so players will experiment and learn on their own (the thrall solidying under light for example, is a great mechanic and taught with no words at all). Absolutely give yourself kudos on your overarching design over multiple levels and pacing.
