What: Diamond Hollow II by Arkeus
Here's the thing about this game: it tricks you into playing it because it has the word 'diamond' in the title. You think it's going to be pretty and nice and kind of glamorous and ladylike and sweet smelling, like a gardenia. But then it's just like any game. You're supposed to kill stuff and collect points but the primitive animation makes it hard to tell the difference between the diamonds and the bad guys so you get confused and die many times over. Then you just give up.
Also, the diamonds in this game are the color brown.
Gameplay: Use arrow keys to move and the mouse to shoot.
