Hello! I played through (most of) this and I'd like to share my feedback regarding the puzzles. I'll say that most of the puzzles are solid, there were just a few hangups.
- The weakest puzzle was the one where you're shown some "maps" and you have to traverse a long distance through a town and some grass. It wasn't much of a puzzle, and I enjoyed the little block pushing puzzle at the end much more haha. Also, I think its supposed to spawn some portals to help me get back, but they didn't work so I had to walk all the way back.
- The puzzle with the 6 panels that you have to configure to have the dot in the right position needs something to designate which direction is "up" in the world. I did the whole puzzle upside down and it didn't register so I had to run around and do it a second time.
- Some puzzles require you to look at one thing while interacting with another thing. This isn't bad in-and-of itself, but the depth of field effect can make this difficult sometimes.
- The only puzzle I was unable to complete was the second half of the locker room puzzle with the wooden blocks. I assume I'm supposed to enter something regarding Vincent Van Gogh's birth and death dates, but it's not clear exactly what, and it's a pretty slow input process with the blocks, so I kind of ran out of steam there.
I really enjoyed the game!
