The aesthetic of this little toy seems like it would have fit a couple of album releases called "Friends in Bellwoods" that were all inspired by the park and the neighbourhood around it.
Glad you caught the reference! I was born in Toronto and Trinity Bellwoods is one of my favourite spots in the summer. The name also has a second meaning with the sound as you noted.
I can't take credit, it was @mlissa_h who suggested the name!
This is an enchanting game. If you are interested in the code, I found the github and the author was generous to share the source code for educational purposes https://github.com/mattdesl/bellwoods
Mostly through experimentation. I ended up with a set of notes that I liked and give enough variety when played semi-randomly, while still keeping with the happy/uplifting mood of the game.
The terrain is bounded by walls (a design decision to keep users from getting too far away from portals) but you can discover new palettes and worlds forever, by continuing to step through unexplored portals.
I wondered about this, too, after running into the edges. I thought they would have made it "infinitely" generating, like with a periodic boundary or some tessellated space.
