This game has excellent graphics, and I was really excited to play it, but the jumps in Bob's room are just brutal. I made it no farther than that. It took me a few minutes to get to the top, where I was told to go back down, get the notes, and come back up. I couldn't do it at all.
I would politely suggest making the platforms wider, and decreasing the distance/height between them. It's just far too difficult to land any single jump as is.
There's also a small bug(?) where people will just keep repeating their dialogue in the same text box if you continue to press Z. No big deal, just didn't know if you were aware!
But I do want to reiterate that you killed it with the artwork. Especially the first room with the forklifts and boxes. Gorgeous!
