At first I thought this would be your regular metroidvania but the truth is that this game is a jewel, it has everything you would want from this genre. Game starts a bit easy for the first hours, a good way to introduce it.. then after you beat the 2nd boss the difficult boosts and I love it. Every retro gamer (as myself) will feel at "home", one of things a love most is the music, is awesome!! very ninja gaiden style. My first 5hrs were a bit rough as I found a glitch in the 2nd boss (details in the forum) and I had to start again but then I got to where I was in a bit more than half the time of my previous game. Overall I would really recommend this game to anyone looking for an 8 bit original classic adventure and for 7usd this game is really under priced.
