I like the concept, and the Kaiju on stilts is hilarious!
Like others, I found the inability to know what's coming was too severe for a jump to be anything but luck, but I can see why you went for the chase cam as you did.
Two possible ways you could resolve it might be:
1/ You could pull the camera back a little so that you can see the building just before you have to jump (effectively the method used by Crash Bandicoot), though you'd probably need to cartoonishly oversize the player character as they're already quite small on screen.
2/ Alternately (or maybe even in addition) you could make the procedural buildings spawn from a seeded random number, so that they're the same every time until you try a new "level" (seed). That would at least allow players to learn the sequence and get good at it, while barely changing how you're generating them. This also opens up the potential for comparing scores competitively, if you wanted to go down that route.
