What to put in credits, if there's only me?

OddConfection said what I was thinking

In order to release the game for PC do we need to legally register an one man company in my country?

—, I am not from Brazil so I am not sure, but I would think it is better to register as it will protect you from the law and copycats if your game is a success. Best to check with a local lawyer, or search some local forums that have sub forums on this matter.

Probably, the best option indeed.

Don't forget your brand

How familiar is "EA sports - it's in the game"

Brand is important no matter how big your company

Push your brand at every chance you can. The loading screen, make a screen before the game that has your logo, the settings page or instructions page. You can also have your logo on the game preview images within Google Play.

If you come up with a popular game you will be glad that your brand is embeded within the project.

Think big from the beginning.
