Ooooh, this is a really fun idea! :D The idea of blocking Medusa's sight is really cool! Enjoyed this as a fun lil puzzle game. :> It was a little hard telling what was going on sometimes. Like sometimes I thought I was screwed, Medusa approached me with the mirror nearby and I won anyways. ^^' Some more feedback on that could be nice. :>
But nice soundtrack, SFX and NES aesthetics. I liked it! ^^
