I'm finally "done" haha. Or I should say, every level, the boss fight, and the title and end screens are completed! I'll probably put it up as a project in the next day or two if anyone wants to play it early lol. But it can be played through multiple times so it definitely seems to be working. There is still a lot I want to do now though, in addition to stuff like finishing the music.
I did get a fourth song written and produced so now I only need like 8 more haha. I also need to add more sound effects and do a bunch more playtesting, but I'm happy to say I can submit something now haha!
