I suppose the fact that I wrote the music in mine makes it kinda fits here, though I didn't write it during the jam. I really like the feel of making everything that goes into my art, or at least as much of it as I can, but I got into music rather late. To compensate I've been periodically just going into LMMS and writing whatever comes to mind as practice, always with game/vn background music of the sort I like in mind, then labeling them with a number to indicate how many attempts I've made. The track here in game is attempt 91, "slow river".

I actually did write an attempt during the jam, because I spent a whole bunch of time brainstorming via creating assets, but I cut most of the ideas for time. What was supposed to be a horror game that starts relaxing as contrast became just relaxing. The one from during the jam was going to take place in a haunted mansion/castle thing, preceded by a track with occasional music box isolated measures with a grandfather clock sound, and cuing the moment a poltergeist started throwing chairs and pianos at the player. I'll go ahead and post it in case anyone would like to hear:
