How do you get in the fourth island of stick rpg 2

On the 3rd Island, near the bank there is a path. Go through there to the 4th Island. To get inside the buildings on the 4th Island you need the Director's Cut. You can either buy it or download it (go on YouTube to see how). There are many AWESOME buildings on the 4th island:
The Brand New Abandoned Warehouse- If you beat it you get a hyper drive.
Giovanni Bakery- You can buy angel/devil food cake here to increase or decrease your karma. You can also buy pecan pie to up all your stats by 30.
The Dangling Pianist- You can get a job here as a pianist, buy a Benjamin Club membership, buy weapons (like a glowy sword) in the boy's bathroom and buy beer (it also has a positive increase in charm). You can also get a Chainsaw Club membership, but only if you have a chainsaw.
