This is incredible, thanks for creating. I can see the relationship between this project and the ax project for the toy box jam :) I loved the secrets the full map is brilliant :)
I also loved the nonviolence idea of the game, and focusing on exploration only, and finally, the ATARI aesthetics which I am a big fond of it. As I always marveled with all the limitations on the console people designed great games that play different, feel different, and look different. Each sprite and pixel counted in it.
Overall, great job :)
