This is the place where you can leave your feedback, bug reports, suggestions or whatever else. You don't need to put any contact info in there, but remember I can't reply back to you if I don't know how to contact you. Don't abuse this feature, it would literally be a waste of your time.
If you have a Reddit account, you can contact me on Reddit instead at /u/CarnivalNightZone. It could take up to a week for me to read replies through this form system.
