Desc: This is an alternate version of the same theme. I realize that the version that was uploaded here by Heart herself is different to the one on YouTube or in-game. So, I decided to upload this version to SoundCloud myself. Also, thanks to someone who point out this fact from the original theme. I wouldn't have realized it myself.

Heart Plus Up! 'Gelatinous Monarch' Theme of King Slime (in-game version)

I present to you my longest running project. I began composing this back in February 2023 and since then, it has gone through numerous iterations. It is very interesting to look back at its older versions and see how I've improved as a composer over time. This was an overall fun track to compose.

We're keeping up the momentum with the Unimush tracks. I made Imitation during my very last week of high school, so I was quite emotional. I'd say it represents my state during those few days perfectly. I'm happy with how it turned out and I'm looking forward to what comes next.

My first contribution to the Unofficial Calamity Mod Music project, and something that's not a remix and Terraria-related at the same time! I had fun making this one, especially because it brought me a bit outside my comfort zone.
