Good, but too small
Nice game, I could do the beginner easily, but I've no idea how to go about the advanced. The problem is the lack of content, e.g. there's only really two levels, one of which seems (to me) near impossible. It also couldn't harm to put in some nicer visuals, like sliding the blocks, and making them look more rounded and shiny. At the moment it looks like games you'd get with a Windows 3.1 computer
