LunarRedMage/Astromeow - The base idea for this quest came from playing Funshine and watching a Let's Play of Lyrics of Death (guess I might as well thank Eddy too

). So yeah, major shoutouts to those quests and questmakers. You should give them a try.
Russ - I can't thank Russ enough for his moral support during the whole development process. It was incredibly taxing as I said earlier and talking with him and showing my progress really helped me get through it. He also did a playtesting run which gave me valuable feedback and helped me squash some bugs when there wasn't much time left to test it myself.
Evan20000 - I talked with Evan more during the beginning of development (technically before development) and he had some good suggestions and feedback. He also provided my with a rare Pepe MIDI that I used for a boss.
Aevin - As well as providing moral support like Russ, Aevin completely reproduced a broken MIDI for me. It turned out to be my favorite in the quest.
ZoriaRPG - Zoria gave some important feedback on my sideview enemy pack which ultimately made up 90% of the enemies in the quest. He also answered some questions I had over the course of the quest's development that helped some scripts get written faster.
Culex - He wasn't the final boss.
