Tip: If you give a Muncher tile custom graphics, it will still act like a coin when a silver P-switch is active, whether it looks like a coin or not. So make sure to use ExAnimation if there's a silver P-switch in the area.
I had a lot of fun with this hack until the Titanic Monarch fortress. While the sections in it are cool, I'm just not a fan of having to redo so much every time I blindly run into the next obstacle. I eventually gave up after getting to the fourth room and dying immediately, and savestated to see what was after that. Glad I did, because the fifth room had a couple obstacles that would have taken me a while to get right even if I didn't have to beat four consecutive rooms every single attempt.
It was a kind of jarring experience because the checkpoint placement had been very good up until that point, and it was sad to end my experience with this hack on a sour note. I did have a few gripes with some of the obstacles (e.g. what was I actually supposed to do with the four fireballs in the second half of sediment valley?) but nothing outside the normal gripes I have with kaizo levels.
