I played Garten of Banban 4 and found all secrets including all drone hats, secret tapes and also Syringeon's secret room. In chapter 4 there are many puzzles and secrets. The new monsters are the jester Bittergiggle, the humanoid toad Sheriff Toadster and the kangaroo Queen Bouncelia. The game feels more like a short movie and the story gets even more interesting.
