Oh...i didnt realized it until now, yes, indeed there is a how to play screen in the title screen, my bad. Tho it doesnt say all the sceneraios, i had several different winning messages, and i didnt know what they ment until i keept getting them. Also sometimes i won without doing anything, perhaps a glitch of some sort?
You can maybe expand this game a bit more if you find something interesting to implement, i would love to see it. I cant think of something, but perhaps your brilliant minds can come up with something.
