@reheated exactly! You're guaranteed to get the symbols you need eventually, and as the game progresses that eventually gets longer and longer. And each time the deck draws all the way out the game bails you out a little bit (actually there are two decks dealing at the same time, but when one ends things should be more balanced). Thanks for your kind words, glad you liked it! :)
I had wanted to put in levels, some explanation of how things worked, and growing numbers of symbols, but ran out of time. This was my first ever Unity project and I installed it a few hours in so a lot of my time got sucked into stackoverflow and youtube tutorials haha, but it was fun to make! Thanks all!
