Oh my god i absolutely loved this entry one of my faves so far!
I think the presentation is both super pretty and also manages to add some intriguing story building at the same time with so little, I love how the cardboard both adds a cute miniature experiment vibe but also builds onto the everything is fake undertone.
The portal influence there it really shines through, especially with the characters I really loved the voice acting it was really fun and well done, I think it successfully captured that vibe! This is by far my favorite use of the theme from a narrative stand point. even if I could tell where the story is headed, I thought the way it was presented was still super fun and it had me hooked!
At first I found the puzzles to be a bit obtuse but I decided to not give up and really try to think outside of the box and my patience has been rewarded, I really appreciated the cleverness of the puzzles once I found the solution . the only puzzle I had to look up was the one in room 5, I really appreciate that you left solutions on the itch page, I was so close to figuring that one out on my own but I didn't think of going about it that exact way lol
