A very shiny little action game!
I wasn't terribly sure of all the mechanics (what is with the sarcophagus anyways?) but it seems like things were thought out. And yeah I can see what others are saying about Spelunky vibes, though I do wish I knocked enemies back a little on hit, haha.
My only major complaint is I think you should render an outline around the text, kinda hard to see your health when it's up against a wall.
