The visuals are nice and the movement was quite smooth. It was quite nice to roll around.
For the notes, I think there were 3 of them scattered around. I wasn't able to read most of it because the moment I walked into it, the textbox pops up. But then I happened to press another movement button because I wanted to change directions to crush a rat, and then the textbox is gone. Might need to freeze player inputs the moment the textbox appears. And perhaps since it is a note and does not really affect the doors, it doesn't need to disappear? Also, the brief text I managed to see, I saw some square boxes in some of the words which I don't know if its done intentionally to omit some of the letters or maybe the font isn't readable?
The stairs was a bit clunky. Maybe instead of those stairs, it could be a door to the stairway, where instead of taking you to another room, it takes you upstairs or downstairs? Idk.
There was a meter at the bottom right, but I don't know what it does?
Overall it was quite fun and I enjoyed it.
