Hey there! It seems that your game can't play without a very critical OpenAL32.dll. Luckily, as a MonoGame developer I have a copy always handy. Place this next to the game executable to be able to run the game.

If you don't trust my link, that's okay, you can go to https://www.openal.org/downloads/ to install OpenAL on your computer.
