Thanks for the suggestion, Josh! I actually thought of that as well, but I couldn't find a way to make it work without using barriers outside the pink ball-on-blue wall aesthetic or removing ice spaces entirely. If there's a way you can think of to make it happen with those conditions, feel free to let me know!
In the meantime, I've updated the set to version 0.8.0 with 10 new levels, as well as posted a minor change to Same Mold Story that takes mmoraleta's suggestion into account. Enjoy playing!
