Hey guys, just gonna throw this out there, I a professional musician, and audio engineer, and if you need music and sound FX, I'd be more than happy to work on your project. I've worked with several developers using Construct 2, so I understand what you need.
We all want to make our living doing what we love, and letting someone else handle the HUGE task of writing the music, and hand crafting the sounds for your game lets you focus on the more important task - making the game! I work quickly and provide options for you to choose from.
