Thanks for the bug reports and feedback. There seems to be various bugs with things not being triggered properly in the 2nd half of game. Tbh I didn't test the 2nd half at all as I rushed it out for Parody Jam. Next update will fix the conditional bugs and add all the verb commands you tried. The backroom section is meant to be obtuse however so seems to be doing its job.
As far as I'm aware with the scrolling bug, that might be due to a longstanding bug with Adventuron. I believe keeping the game in fullscreen would help prevent it unless you've played it that way the whole time?
The Father Roach "poetry" was just Papa Roach lyrics copied into the game's context. I suspect the original game's "Father Roache" was a reference to the band but more exaggerated here.
You're not far off from completing the game but sounds like not triggering properly. "Look Hole" should have been the solution in that room.
