That was a very polished experience, from the start screen to the notes to the light/dark effects. The fonts were nice and the sound effects and music were good. The low-poly graphics with great lighting worked really well. The hidden clues that were revealed when the light was off was a great idea, reminiscent of escape rooms. You did well on the theme with the light/dark mechanics.
We struggled with the free look being locked and being a bit sensitive, so we had trouble putting the mouse on the combination lock to turn the dials. Centring the view when you moved would have been good. The view restriction (45 degrees left/right) was slightly uncomfortable to play with. The steps were very small and the lack of keyboard repeat made it slow, unresponsive and a bit frustrating to walk around.
We're not sure how big the game was because we never got past the door, despite play attempts. We always ran out of lantern charge before we could progress.
Well done on producing such a great looking and stylistic game. We'd play it again if it was a bit easier to progress in.
