So,still now news on the music editor. But now I've managed to get some time to start working on level design. I got to take inspiration from the film.
There's still much to do with the graphics as well. The bosses need to be replaced with characters from Yellow Submarine.
I'll get by... with a little help from my friends.
PM me if you're interested in helping out with this project. I've started a discord and I can send you a link if you wish to help or want to see the process.
