Excellent game!
Orbis Venatus was a very enjoyable game to play. I'm not usually a big fan of maze games, but this one seemed to have a different aspect to it that really kept me playing it.
I liked all the different level designs, not to mention all the little nooks and crannies thrown in there to make the game more difficult as you continue on. They were simple, but challenging nonetheless. As for the music, the selections that you used really seemed to gel well with the game's design.
Overall, it was an enjoyable game to play.
