Vengeful Guardian: Moonrider is a lovely tribute to Shinobi and to many retro hack & slash games. The 16-bit art is amazing, even better if you turn on the CRT filter. Movement is fluid and levels have a simple yet well made design, although some platforming bits might get quite frustrating. I wish it was more difficult and maybe longer though, since you can finish this game in just around 3-5 hours. Getting a good rank in the stages isn't that simple at first, you need a couple runs to understand what to do in order to get As or to do even better.
