Akuya

The game looks nice but this is as far as it goes. You are not able to do anything except get your flash light out and put on a helmet to go in to the sea. This is very much in pre Alpha and should not have been added to steam just yet as the game is not playable You are not able to pick anything up on the island that you start on. Lucky for me I got this when it was in the sale. I really hope the developer continues to work on this game as it could have potential.

I walked over the edge of the world and fell down infinitively

It's not just "not a game", it also isn't interesting or interactive in any meaningful way.

If you compare the game trailer and screenshots on the Store page for Akuya and compare them to the contents of the game, you will find that the majority of the advertised content does not exist in-game. There is a forest level shown in the trailer, but no way to get there. There is also some sort of fish shown (not the shark) that does not appear in the game. Besides the false advertising, there is nothing that the player can really do in Akuya. But that's all Steam games nowadays. 0/0 does not exist

just an island, nothing you can do.

Akuya is a scam/abandoned EA/joke/demo game where you're on a small island with nothing to do (note: the screen shots above are not from the game, very misleading). There's literally nothing to do in the game but move around and look at 3D asset flip style objects. Inexplicable why Valve would permit this on Steam.
