4/5 because at the current stage of development, it's very very good. i see a lot of exellent suggestions for improvements in the comments, though; it's far from a complete game.
i'd love to be able to see how many new conbinations i can make with each major category. either total, with the ones i've already done subtracted, or the number of currently available new ones...
i must admit i raised an eyebrow when gozilla and nerdook got married :> . i'd like to see more upgrades, or bigger goals, but it's an excellent little time waster.
i wish i had a little more control over the blocks i'm given. like a power-up, or the ability to choose one or two kinds of units to "leave behind" and not use, giving me more of the useful ones. nice concept, but needs a lot of work.
this game certainly has potential, but i just don't understand the game mechanics. a quick explanation would easily raise my rating from 3/5 to 4/5, or even higher. without a basic understanding of how the mechanics work, i can't really tell how good it is.
