definitelynotnewvegas indeed.

How do I get this achievement? I'm assuming I have to defeat all enemies in the first level based on the other two secret achievements, but the little slimes keep respawning.

Thanks to Jim Sterling and his 2018 Game of the Year Awards.

really cool game, a bit short though, id love to see it taken further.

In windows 7 just click the volume button, on bottom right of your screen and mute it there. In windows 10, download winaero tweaker, find and download the old volume controle button back (so you get it back from how it was in windows 7) and again mute it from there. ...
