I've lurked and posted here for a while now, but I've never actually shared my project, which seems silly to me in retrospect. We've been working on a comedy action-RPG (that sort of falls into the Metroidvania category as well), and I've been using Monogame since.. October of 2015 I think? We started development in 2014 and I had been using XNA until the Monogame switch.
Here's a pretty comprehensive gallery of gifs that explain the game mechanics
Here's a link to our devlog which more stuff, which I update at least once a week.
And here's a gif that I'm proud of in particular. I wrote a function that wraps and scrolls text, while also supporting different font styles and colors in the same string. Italics and bold characters help get humor across in some cases, so it was important for me to figure that out.
Anywho, I can update more development-related code things here I suppose, but there's a chance I could meet some of you at GDC/PAX/somewhere in the future so I wanted to share what I'm working on regardless.
