Space Pips borrows quite a bit from Geometry Wars, but not without giving credit. It's a somewhat casual take on the theme; you get a health bar instead of a supply of lives, and the shop lets you customize your progress to a certain degree. Two things the game really needs: an audible indicator whenever your pip total passes 100, since that's the magic number for purchases; and some visual warning when a bad guy is about to appear. When you're moving, which you always should be, you simply don't have enough time to react to some nasty critter popping into existence a millimeter from your port bow, especially when it's got a flippin' shield.
To make you feel better, collecting space pips makes a magical, soothing sound, like wind chimes. "Have some more pips," the game seems to be telling you, "the wealthier you are, the more comfortable you'll be when I kill you." What a lovely gesture. And a valuable life lesson as well!
