Sweet!! I think in concept alone this game is great, and scratches an itch I didn't know I had. It reminds me of those classic point and click escape rooms I loved as a child, but combined with the added 3D ability to climb onto the bed and look around made it feel more engaging.
I think it'd also be really fun if you could crouch to look under things! (Such a simple small suggestion I know but I really want to do it for some reason...)
The fingernail bit made me grimace, I'm excited to see the finished project!
