I just finished my second game!
For the Number Wizard UI project I chose a retro 1980s computer theme where a newly developed super computer (the Guesstimator3000) taunts you for being of the inferior human species and boasts that it can read your mind.
I actually created two sets of scenes for this game, those to publish to a standalone build (with quit buttons) and scenes for the WebGL build which omit the quit buttons as they are unneeded.
Let me know what you think
