This is also part of a larger collab which will release on Undertale's anniversary in about a month. I'm working on another song that will be in there as well and posted when it comes out.

The old Mario Paint Composer is gone, but there's a new one that has been worked on for a while now which added a lot of improvement and quality of life updates. You can find it here https://github.com/DC37/Super-Mario-Paint/releases .

There is also the Mario Paint discord server where a lot of us hang out https://discord.gg/pqxdZvQ
