Controls make it better than the GBA version, though not having a score on every level made it less challenging.

Rolled credits at 3h43m, will do the plus levels here instead of on GBA.

edit: full playtime at 7:17. Finished every level with the gold star. Not going to do the time trials anytime soon -- I enjoy this game but it's too much MvDK in a short period of time lol
