I too have some notes. First the negatives:
- It was a bit disappointing that finding the tetris lock pieces boiled down to just looking on shelves and behind things.
- Speaking of the tetris lock, getting a preview highlight of the held piece while placing it would have been nice.
- The placeholder t-pose was pretty distracting, thanks to the omnipresent shadow, though I guess it had to be there for the mirrors.
- Took me a bit to realize there was sprinting and jumping. My expectation for this sort of game is that you're limited to walking. Not sure that's a problem, but something to consider?
- Could have benefited from some more ambient noise or music. The silence got deafening after a while, with the occasional door creak only reminding me of it. Footsteps, rain outside, anything really.
On the positive side:
- The Amnesia style world interactivity was a good choice and worked well.
- Once I figured out I just had to look for the tetris pieces, things slid right into place. Escape room games have a bad habit of relying on moon logic, but this game made sense.
- I liked the mirror transition, and the subtle difference in lighting helping to differentiate between the normal and mirrored bathrooms.
- The box glowing on the inside was an effective way of marking it as weird and unusual.
- While they were a bit hard to spot, every room having a light-switch is handy for marking where I've been.
- 3d gets a bonus point :]
Maybe a bit too short, but that's better than a puzzle game you don't finish. A great first time entry, if you ask me :]
