Thank you!
Hi! I'm flattered that you asked for a release. I've made an EP with the tracks here: https://soundcloud.com/vidarn/sets/mirror-city-ost
As for my game making tools, I'm using a little engine I've written myself over the years. It's programmed in C and uses OpenGL as a graphics library.
The art and music are also made using some tools I've written myself. They are quite simple but I find them nice to use since they are built directly into the engine and I don't have to export/import files to get stuff into the game.
