Quoting Nintendo Life's review:
"La Mulana's WiiWare release has been a rocky road. It was first announced by developer Nigoro in 2009 and suffered several delays before finally hitting the service in Japan in 2011. Of course, most were expecting it to be released elsewhere soon after, but that didn't happen. It was eventually cancelled by its old publisher Nicalis earlier this year, before then immediately being picked up by EnjoyUp Games and finally seeing a western release a few months later. Has it been worth the wait?
This version of La-Mulana is a remake of a freeware PC game with the same name, originally released in 2005. Heavily inspired by the MSX system, which was very popular in Japan, and especially Konami's Maze of Galious which was released on it, it can most simply be described as a Metroidvania game with a large emphasis on puzzle solving. The original freeware version featured MSX-like graphics and sound, but this remake has visuals on a level comparable to Super NES, and almost CD-quality music." 10/10
