It's probably just Unity (Defend your Lab also has this issue, but to a lesser extent), but for some reason this hogs up about 2-3GB RAM on boot.
Visuals and music are quite nice, but I can't seem to progress much in this game. It won't let me buy any equipment and whenever my initial thingy breaks it won't let me repair it. I'm using Chrome on windows. Any clue :(? I'd like to properly play it before rating.
