I'm not sure whether I have the original or some fixed version, but I noticed one minor mistake:
when played in normal mode, there are some animals at x1006y995 that walk on air.
Now to the level itself:
The tilesets, backgrounds and custom objects are all great and incredibly creative. Lasers and those pink fish flyers turned into traps in that temple are my favourite, that falling flowers and sinking turtles are also very funny.
I liked the story and how different are paths of the characters based on their abilities.
Those cinematic cutscenes (well, not really cutscenes, but..) were the best since Shipwrecked. What is it with the levels set on tropical islands being so good?
I got the worst ending so far. Does the ending I got depend on the choices during the whole game or on the challenges in the end only?
Incredible level! However, looks like I'm stuck: I returned to x1009y994 with the girl and there doesn't seem to be a way out. (yep, must be a bug, I cheated my way out of it)
Lacking save spots: on the right side of x1009y1003, in x1009y1015, in x997y1006 (after the slow walking, of utmost necessity).
Proper difficulty is Very Hard/Very Hard (Very Hard rooms are still present in "Casual")
Edit:
I did it, got all endings, not all GCs and not all trials yet. Another lacking necessary save spot is before Edward's 10 second trials on Very Hard. Since that goes against the rules of the trials, instead I think he should go first or there should be a choice of who goes first (between 2 males), then the other 2 people are chosen by the devil.
