Thanks for playing! I'm glad you enjoyed the game. You can find the devlogs on the game's store page just under the download section, though they're mostly just patch notes with some design discussion.
MonoGame is great in terms of the amount of freedom it gives you to make what you want from scratch, but that also means you have to deal with some annoying technical stuff most engines would take care of for you. The default audio API in particular isn't very good, so it's recommended that you use some type of audio middleware.
If you need help getting started, I used GameFromScratch's tutorial series on YouTube. There's also plenty of documentation of the MonoGame website.
Sorry for the late response!
