I mean, this is clearly inspired by Megaman games and I'm in love with that saga, so this is my favorite game so far. I just rated it with the best possible rate. You did a GREAT job in every part of the game (though the last boss was the easiest one), but yeah, everything is just perfect. Graphics, music.
I even had to switch to my joystick because I was not able to beat the game with Keyboard and I WANTED to finish it :)
Congratulations.
