g r e e t i n g s, Furry One. Your suffering amused me greatly, and your resolve in the fight impressed me.
First of all, the you had the right idea about the stairs. They're top jank atm, and going up/down some of them requires mashing up/down and Z in the general area for a bit. Examples: 17:43 (you can go up to the red blinky) and 6:35 (that's a stair down, try the left side). Thanks for bringing that to light though.
And as far as "boss" "fights" go, they're optional, but some paths require you to beat them. You can "reach" AN "end" without them.
If you figure out the meaning of anything in there, please let me know.
Also, the delay between the bg noise loops is a bug. If that bothers you too much, it's fixed when playing the "game" through EasyRPG.
Glad you liked the music too. Looking forward to seeing you delve deeper...
