At least until we make our own.

The retroachievements site has developed an entry for this particular game, and along it are leaderboards for each "bosses" of the game (minus Garlen for some reason) and the three of the five extras. So if you want to have fun running against other players, this will be it. I assume they get their time via the the in-game timer. There are no equivalent to this for EoD. You will need RetroArch and if you actually want to register your times there, but you can probably play along just fine
