This one has sat in my unsorted games folder for a very long time because I didn't have much success playing it. You play a priestess who has to collect colored spells in order to banish enemies. Your only controls are the arrow keys to move and the space bar to jump (although return does skip cut scenes.) The problem is, banishing monsters seems to be an odd affair... you can just run into them if you have the right spell to banish them... kind of. Sometimes, this just results in you dying. I'm not sure if some of them have to be attacked from a specific angle or what.
There's also a partial review of this game here with some additional screenshots.
