My first impression is that it's very small and hard to see. It seems there was some sort of error, so I don't think it's a problem with the game. Probably an issue with itch. The actual game is only a small part of the game window, the rest just being black. I attached a screenshot for reference.
For movement, I felt the jump was very, very high relative to the scale of the game. It also felt really hard to tell what objects were collideable vs just background objects. I couldnt really tell until I bumped into them. For example, I think it was a trophy case that I thought was a part of the background, but it turned out to be collideable and that I had to jump over it, which I felt didn't make much sense.
Also, the game ends as soon as I check the texts, I think? Or at least, it freezes. The video had you lookign for a wallet afterward, but as soon as I check the texts it just says "Thank you for playing", and doesn't progress.
I wasn't able to play long enough to check the gamefeel, but I do like the atmosphere. I did enjoy reading about the planned additions, and I think it would make a very good game once you add a few and polish a bit. If you do plan on continuing developing, I'd love to play it later!
