Hungry Blocks

I've always loved games where you start small, and by eating increasingly larger enemies, grow. (Hence my penchant for the Katamari Damacy games on PS2) Hungry Blocks is one of these, but with the added effect of color coding. You are the yellow block. You eat the green blocks. You get eaten by the red blocks. The cool part is that as you eat green blocks, you'll see more and more of the red ones switch color. Of course, as you grow, it will also be more difficult to avoid the bigger blocks!
