I started making Monogame (Including XNA) games for more than 10 years but never released any, but today, I released my first game made in Monogame, Space Bugs Wars, and it is free for download from
Also I release YouTube videos every week, I talk about indie game development and I focus on different topics that may be of your interest , if you are demotivated or stressed out while making your games take a look at my videos, some may give you some laughs. You can watch about Space Bugs Wars in YouTube and I made this game in 3 and a half weeks. My plan is to release one game a month and this is the first one.
