As the site is currently defined, I believe this would be off-topic. The game, from what I've researched of it, appears to be a card game and does not really fit in with other RPGs.
Particularly, this site's FAQ specifies that it is meant for pen-and-paper tabletop RPGs. See the quote below.
Role-playing Games Stack Exchange is for players and gamemasters of tabletop role-playing games. If you play or run Dungeons & Dragons, Shadowrun, World of Darkness, or any of the thousands of other pen-and-paper RPGs, then you're in the right place to ask your question!

So, unless we want to broaden the scope of our site definition, and update the FAQ accordingly, "Aye, Dark Overlord!" would not fit in here.
Other, notable differences from commonly-recognized RPGs (specifically D&D, but I'm sure this applies to many others):
- No persistent characters/world - Every session is a one-off.
- No character creation/generation. (In part due to bullet #1.)
- No unique background story, or much room to make one - Every session follows identical theme and play.
- No actual "world" involved - Games take place in a single room, the Overlord's lair.
Perhaps the "pen-and-paper" stipulation mentioned above may be removed or modified (see this thread for discussion), but even if that were not an issue, Aye! Dark Overlord still does not IMHO qualify as an RPG for the purposes of this board.
