is there anything more to this game then fighting the same one enemy over and over, getting the same loot over and over and having sex with npcs?
what is the 1/20? i assume it must be some sort of level up system, and is there a way to masturbate in the game?
Nope, you pretty much nailed the description on all of the content in the game. People have been posting various NPCs that they have created, so you can scroll back through the thread and download a few, if you want to change up the default NPCs in the game.
There is an NPC creator you can use in the game that lets you create your own NPCs that can be added to the pool of available NPCs to spawn on any particular island.
The 1/20 is the map level. There are 20 'different' islands that you can potentially go to. The major difference is that on the higher level islands, enemies drop more money and the gear is a bit better quality.
To increase your level, you need to pick up enough of those pink energy balls that are floating all over the place on the various islands and then click on the central column at the island's portal to fill up a progress bar and advance to another island.
There is an option to masturbate, but you have to interact with a NPC on the islands. I THINK the option is under Offer, there should be an 'ask the NPC to masturbate' or just masturbate. When you are just slumming around one of the islands, I don't think there is an option to just rub one out wherever you are.
