Shoot spikes for love.
The Courtship is another Flash game by Ethan. It is a shooter-platformer game, but instead of gunning down the baddies, you gun down obstacles to clear your way to the exit.
A large stream of 80 revisitable levels should be enough to keep you going for an afternoon or two. Some are difficult, some are not, some even require you to think a little.
