Yep, it's the number guessing game from that Unity course. You just basically pick a number in your head then the computer will try to guess it. If it can't guess it in 15 tries, you win. Simple as it sounds. By the way, here's the link to the project page: https://kraken55.itch.io/numbers
Unlike other people who published this from the course, I'll try to improve it. Adding more functions, making the game better.
