Did not expect a game about an underwater alien city to ressemble the 1920s but here we are! Really liked the gameplay on this one, the game not really telling you what to do works in it's advantage, really letting the player find the surprise on his own. The ending also really surprise me, did not expect it to end like this.
I also like the visuals, it's just simple enough to allow the player to fill the gaps himself and it's also really out there (duck-alien costume lol).
As for the ending question, I think you should continue this! If you can integrate more weapons and push the settings of the water city, I feel like we could get a great experience!
Good job on the game!
