Like Whack-A-Mole, only nuts
Tontie is this crazy-ass free game that Frank turned me on to earlier today. The basic premise is not unlike Whack-A-Mole, but with the volume turned up to 11.
The game maps to your keyboard's number pad, and is set up in a 3x3 grid. Little bug-eyed monsters -- cute little baby versions of Sky Deviler from Kaiju Big Battel (well, that's what it looks like to me, anyway) pop up on the grid, and you have to hit the corresponding key on your keyboard to whack them with your hammer. Sometimes you'll get a coin, sometimes some extra health. If you hit the wrong space, you'll lose some health.
This quickly ramps up with red monsters, yellow monsters, mines and other stuff -- the challenge on this game ramps up really fast. You can also power up your gear or charge up your health by trading in your coins at little shops that will appear on the game-grid occasionally.
When it gets really nuts is when these little things pop up with numbers in them. You have to hit the number on your keyboard, then remember to hit the number that corresponds to the space on the grid where the object is to make it disappear.
Give it a shot. It'll make your ganglia twitch!
