On the one hand, the care and dedication that's gone into recreating He-Man as an indie side scrolling arcade game is enough to bring a tear to my eye. On the other, as a commenter points out, "you do know that something called 'copyright' exists?"
It's a beautiful looking thing with the current demo including 10 story stages, 28 versus mode stages and boss battles, all accessed through a full map of Eternia. It's also got a playable He-Man, Man-At-Arms, BattleCat, Sorceress, Skeletor, Evil-Lyn, She-Ra , Ram-Man , Teela, Orko and inexplicable guest star Lion-O.
However, despite the love that's clearly gone into creating this it's hard to find any thing that doesn't breach just about every copyright law going - every sound and image seems to be lifted directly from the show.
Here's some one-on-one action between He-Man and Skeletor:
Here's some side scrolling adventuring:
