Gameplay:
Though the puzzles worked well and had a good variety to them, I think they could have used a bit more explanation in order to solve them.
Story:
The story that's been set up so far in the demo is interesting, though a little light. The reveal at the end makes me wonder what else they have planned for the full game, since the demo already feels like it could work as a standalone game.
Presentation:
I think personally I would have liked if the design fit a theme better, particularly the UI. The ripped up STEM notes on the title screen is a unique idea, and would have looked cool if implemented maybe for the window boxes, as an example. The visuals and music did look and sound decent though.
Horror:
The horror was pretty decent, I think I would have liked a bit more scares personally. But what's there works well for the length of the game.
Overall:
A decent game! There's a couple places that I think could be polished more, but that's mostly me nitpicking. The puzzles, once I figured out how to solve them, were pretty fun!
