I take that back. I gave the game a few more playthroughs, and what's there I'd call /quirks/ more than /bugs/.
You def get stuck at the last screen with no listed way to restart, bounding boxes are... unknown... lives remaining is not visible (nor are score or pages completed), and after about... page 40 or so, you are essentially invincible and really only have to worry about mines, since by that time you max out the upgrades.
Oh, and __more music!__
