This is a very good game but after beating level 5-1 you just reused the first two levels that was very lame... and after collecting all 15 acorns nothing happens :(
(If you are on level 5-1, start the speedrun in the menu and then exit in the 3rd level you appear on level 5-3 in the main game, which can be played for an acorn and you can move back to 5-2 where the same can be done)
