This game has enchanted me since I started the adventure and I still have a lot to complete it, each time the challenges are better, like you I like the music a lot but as a tip do not worry too much about getting everything the first time, at least as far as I think there are many that you will need new skills to get them haha.
I had no idea that Pico 8 is a retro version hahaha, in this one you can also play but as an additional cool that detail :D
I missed a lot of things, I guess... I will take my time with this one. Love it so far. That Pico-8 version was a very short one but was quite interesting.
