This is a re-release of Shounen Ninja Sasuke, a SNES game that was developed by Sunsoft. I realize that this is the first official Western release, but they really should have kept to the original name so that fans of the original could find this game more easily.
This has full gamepad support with Xbox and DualShock controllers. Couch co-op is also available.
I kind of wish CRT filters were available, but at least the 4:3 aspect ratio is preserved.
Also, this has an introductory price of C$6.23, so at least it's cheap.
This is a free game made by students. Even if it's a little rough around this edges, it's worth exploring. Plus, I like the aesthetic -- it reminds me of an old Mac game named Bugdom. There's gamepad support. Not much in the way of features, but again, this is free.
