A quite literally underrated game. (Thank you for publishing a web version by the way)
It is full of charm especially in Brioche's inner monologue, the overworld art, and the VGM. The bark button is peak sound design and UI/UX.
I also got stumped at "Can you see it?" but luckily saw a non-spoiler hint on Discord, and then I finally worked out what the objective was. I like the esoteric narrative framing of the puzzle gameplay, it would be perfect if taught the player a little more clearly without being too obvious. The puzzles got pretty challenging towards the end, and I liked the final puzzle a lot as you sort of develop a mental map as you retry it.
I also accidentally skipped a lot of dialogue, but it's not the end of the world (which I plan to replay to see). I just started rolling my own dialogue system and it's interesting to think about creative implementations for dialogue advancing. I made a crude prototype for normal/faster visible_characters reveal using tweens that doesn't seem like too messy of code.
Also very impressed to see a team of your size coordinate so well. Good job to you all!
