Calling Obake (meaning) a mixture of Super Mario Bros. and Kirby wouldn’t be too misleading. In this platformer you play a ghost who can hop on your enemies’ heads and then (by pressing down) possess them. Other than being cute as hell, there is a lot of diversity in the enemies (moreso than Kirby I would say), and the levels are designed thoughtfully around this idea, with lots of secret passages that can only be accessed with certain skills.
Some of the enemies are just awesome, like the giant pig in a runner’s outfit that charges through blocks, or the monkey who can turn into a lightning bolt. Anything that moves is fair game to our little hero. (Seriously, the pig cracks me up so much. He’s so buff!)
Unfortunately, the game won’t run unless you turn on Japanese language support or you have a pretty old patch. I only managed to find one site that had a patched version of the game. The link is here. But the game still crashes for me on exit, even with the patch.
But it’s worth it!
