That makes a lot of sense! I don’t recall an ending cutscene, but that definitely would’ve tied everything together.
The nonsensical Wonderland thing could totally work! I like the idea of progressing through a series of unique puzzles. After all, the original Alice in Wonderland doesn’t have much of an overarching story at all, and it’s a classic. All it would really need is some sort of through-line to tie a bow on the experience :)
