One Button Bob
Do you want to play a game, but every button on your keyboard has deserted you? As long as you have your trusty mouse by your side, you can still get your platforming on with One Button Bob, created by the maker of the ClickPlay! series, NinjaDoodle. Little Bob is going into a dangerous castle/cave/fortress/never-ending tunnel... thing. Whatever, it's gotta have treasure at the end of its dank corridor, and that's the important thing, right?
Control is with the left mouse button, and the left mouse button only. Give your keyboard the cold shoulder. Let it wonder what it's done to make you so upset. Make it remember the good times of that arrow key controlled RPG. Then hopefully it'll treat you nicer when you play your next frantic button-masher.
One Button Bob is light on instructions; reading the title is more or less instruction enough. Although you only ever use the mouse button, you will have to use it in different ways, sometimes with careful precision and timing, sometimes frantically mashing, sometimes holding. The only way you'll know what to do is by trying.
Oh, and you're going to die. A lot. Poor Bob is a one hit point wonder, and so fussy that even landing slightly off a platform causes him to burst into particles. Sheesh, Bob, suck it up a little. Fortunately, dying just makes you restart at the beginning of the screen, so if you persevere, you will almost certainly make it to the end.
If making it to the end of the game isn't enough, the more hardcore among us can try to beat the game using as few clicks as possible. You're given a score at the end of the game, and if you're unhappy with that, you can easily head back and give it another try. It's a short game with a minimalist presentation, but it delivers entertainment in droves.
