Maldita Castilla EX!!! Cant wait for this. It will be a Day 1 purchase for me for sure. Fantastic spiritual successor to Ghosts N Goblins. Actually the guy who made this has developed some AWESOME games. All of them are free for PC.
I highly recommend The Curse of Issyos as well.
Actually didn't even know what this was. Looked it up upon your recommendation and am definitely intrigued. If this price is right I may just bite.
