I played through
Knytt Stories, or rather the episode that comes with the initial download. I liked it enough to download the other official levels. My only gripe is the complete lack of good choices on resolution. The window is way too small, and although the aspect ratio is very wide, the only fullscreen choice is 4:3 aspect.
I know I've mentioned
Blocksum before. It's a puzzle game where you have to group together
n blocks with a value of
n. (Example: 3 blocks that have "3" written in them.) They rise from the bottom Tetris-Attack-style, and you have to make them go away before they jam up to the top. All you can do is combine blocks together into higher sums, so that the correct number of blocks of a certain value touch together. You can keep stringing them together after the minimum is reached, so you can for example have 10 [2]'s together. Once you figure out the mechanics, it's very addictive, and gets ridiculously hard as higher-numbered blocks start to appear. You won't be wasting hours on a single game, I don't think.
Aha!
Youtube to the rescue. This game is so hard to describe. For those thoroughly confused with my explanation, a movie is worth 1000
2 words.
