I played up till the game switches into 3D. Most of the puzzles I figured out quite easily besides the "talking about me" puzzle which took me sometime. I think it is an interesting dynamic having insecure thoughts as a puzzle. I would keep in mind, people who haven't been at least a decent amount insecure in the past may struggle to figure these puzzles out (hence the other comments).
Bugs I noticed while playing:
- Sometimes when blocks turn green they proceed to flash from purple to green
- in your house the mouse flickers being toggled on and off.
Recommendations:
- Have (Enter) and/or (Space) be able to select things, it doesn't feel natural selecting with the mouse when the cursor is toggled off
- Since you use Unity change the rotating speed of the blocks to "time.DeltaTime" so they don't change speed based on the framerate
- Make it more apparent what the hint block does, it took a while to figure out how to use it
