That reminds me of how Donkey Kong Country 3 allows you to get 105% completion. I wonder what you'll do with Misery of Magic's 105% completion?
As a kind of last-minute addition, I might make a little award for that and a few other things, which is stored in the extra data file and appears in the title screen, kind of like the stars from SS1.
Some other games also have over 100% completion... whether intentional or not...
It arose, basically, because there are a heap of rooms which technically count towards completion but which weren't accounted for in the calculation, and that, under certain conditions, it's possible to get one more weapon than the usual maximum, which also counts towards completion.
For 0.4.11, all I did was fix some of the stuff associated with ending 7 -- for whatever reason it was handling textboxes in a completely different way to everything else.
