i'll see what i can do. the main problem is that we don't have a model or good sprites for boog. the 3d characters are much harder to replicate without either of those. though, i'd like to think no character is impossible.
i can only find one reference for the stage, not sure what milkweed academy looks like on the inside. if i can't figure anything out, i'll make it a reference in kyle's moveset (perhaps he teleports you there) rather than a full stage.
