I saw Janken play this on stream so I knew there was something else on the second loop, but I didn't expect that ending! Good work on the story!
Nice sprite work and world.
Definitely miss the audio to bring together the experience.
You get extra points for including the controls in the game and for the cool gameboy aesthetic.
If you have time, I hope you can polish the game a bit more with maybe cutscenes and music to give a higher weight to each of the bookmarks as they are revealed in the second half of the game.
I enjoyed this game more than I expected! :D
