Oh my goodness, that was it. After finding out that you weren't kidding about how the game gets buried in searches (even with the "Heart of Ruin" added to it), I stumbled across the build you uploaded to Game Jolt, which is 1.2.19 and includes a bunch of other changes, like an existent room 241 and a combo mechanic that shows how many times in a row you hit enemies. Any chance you'll reupload that as an update to Final Columbus over here? EDIT: If you purposely chose to revert back to 1.2.15 for some reason, maybe you could give people the choice of which to download? EDIT 2: On second thought, maybe it'd be better to stick with version 1.2.15 since the upgrade for the Chain Core wasn't implemented (the sidequest seems to stall after giving the Master Floppy to the shopkeeper), meaning you don't get anything for fighting your way through that nonsense. EDIT 5: and the new boss fight against the electric-gun-wielder crashes the game when you try to speak to her afterward, so there's another reason to stick with 1.2.15. EDIT 6: and 1.2.19's credits are missing the comments/descriptions for the enemies/staff, but it does list all the enemies that were missing in 1.2.15's credits.
I guess I only have one more question: 1.2.15 has an unused music track called "sound87" that isn't present in 1.2.19 at all. What's the story behind that track? Was it a prototype of Frozen Hearts, a track for another one of your games that you considered reusing, or something that someone else composed and you included by accident?
