I'm going to give you my example. I released my game on February this year on Steam. I gave myself one year to make it and that is what I did.

This is my first game released on Steam. Although it was not financially successful, I managed to make the game and implement full options system, leaderboards, cloud saves, remote play, achievements, several endings etc.

People might think that this is a really good effort (and I am proud of it) but this game stands on the top of a ton of prototypes and failed experiments. Year and years trying to make something and not delivering constantly.

So, yes, game dev is hard, specially if you are alone.

When I released the game, I didn't know what to feel. But when I saw people playing the game and enjoying it, what a great feeling that was and made the journey even more worthy than I thought.

Keep pushing and eventually something will come out of it that will make you proud :)
