+
+The Mirror is an open-source all-in-one game development platform, providing everything you need out-of-the-box to make a game/3D experiences, even if you've never written code in your life. The impetus behind labeling it an "open-source Roblox & UEFN alternatve" is because these are the two closest examples. Frankly, we're surprised there aren't more examples, especially with good graphics instead defaulting to cartoony styles.
+
+We hope to change that! :)
