My name is Bilge Kaan, I'm from Turkey.
Last month, I released a game called "Indecision.". Normally, I make HTML5 games as a freelancer. I made the game while I was working on freelance jobs. It's a short game but it took me 2 years to finish it. I made it because I like the process of making it. I didn't think people would like it but it gets positive reviews on Steam and got a good review from Kotaku. It didn't make much money compared to my freelance jobs but it sold more then I thought. Even though you can finish it in less than 30 minutes and it costs $3, the refund rate is 10%. It means people loved it or they don't know they can refund games :D I think it's a successful game. So to be successful keep your expectations low, make personal/weird games and have savings.
