La-mulana caused me the most headaches of probably any game I've ever played in my life. I hated that game with a passion at times, and I refused to use a guide. I'm definitely donating to this.
Glad to see some La Mulana 2 backers here! It's a great project.
I first found out about La Mulana on this very forum actually, way back in 2006. I feel that just like Cave Story, they are both made by Indie Japanese developers and released as Freeware originally, but were just so well made that they were both destined be published commercially. I also learned that Amaya-san and Naramura-san are friends, which is also very nice to see. We are hoping that perhaps Amaya-san may lend support to the La Mulana Kickstarter, and also... wouldn't it be great if perhaps this also interested Amaya-san in creating a true sequel to Cave Story using the Kickstarter platform through Nicalis.
