Sorry to hear it wasn't quite what you were expecting. The gameplay principles were simple enough that I felt needed no explanation. An Op is just an operation performed in the cloud service. You may think of the total at the top as a score. Clients requesting Ops (and your machines fulfilling them) creates revenue depending on how much each Op costs. Changing the price affects demand, and so does the services' visibility (an estimate of which is unlocked by a project card).
In the end, it's just another clicker built in a restricted time span. Usually when I participate in this jam, I only get so much time to fine-tune and tweak the game's mechanics after having done the essentials.
