Who Let the Blocks Out?  
One of only two SH entries I still occasionally play, good fun and well made.

Space Glider  
Mmmm, StarGlider 2, Mercenary, early days yet but looks very promising.

Firecrow  
Standard vertical shootemup, but with good excessive visual effects and good weapons. Music is also good (though taken from other stuff). Stop using low res!

Drops of Light  
Very relaxing to play, though the levels that need a lot of moves are tedious. I especially like the music, mellow out to it. A good idea that is well put together.

Operation Black Sun  
Nice gameplay, though slightly spoiled by bad maps and dumb enemies. Definitely has quality. Liked the music and effects too.
