http://www.alienhominid.com/I'm loving this game right now. On one hand, it's quite difficult - there are many instances where you can't avoid dying at some point unless you become obscenely good at the game. On the other, it almost doesn't matter whether or not you die because you have a lot of lives, a lot of continues, and you can load the game from any stage that you have reached previously.
The game is beautiful, too. Check out the website, it has a few screenshots from the game. When something explodes, it doesn't flash for a couple of seconds and then disappear; it really explodes in a ball of flames, sending debris and black smoke all over the screen. Even the mini games rock (Soviet Missile Mastar, or something like that, is an amazing minigame where you guide a small missile through Atari-like graphics, evading airplanes, birds, and other distractions while trying to end up hitting your target. When you do, you're rewarded with a short dance, then a screen with the word "PWNED!". The first time I saw that, I laughed so hard I screwed up on the next missile without even knowing it.)
