Introducing the world’s FIRST and BEST overlay utility designed to reduce 3D motion sickness!

My ex-girlfriend—who is now my wife—used to suffer from severe 3D motion sickness.

I couldn't share the games I had loved my entire life with her.

That was the moment I knew I had to do something.

So I built this utility for her. And now, for all of you.

Don't lose the love of your life over something as small as 3D motion sickness.

This program may cover a small part of your screen...

But it just might show you what true happiness looks like!

• We recommend assigning a hotkey to quickly show or hide Mulmiyac

• Settings and profiles can be synchronized through Steam Cloud

• May conflict with some anti-cheat software (No conflicts have been reported so far)

• Works in most PC environments, including Steam games

• If Windows Defender or another antivirus blocks Mulmiyac, add it to the exclusion list before running it
