I have to say it makes me wanna play the main game
I liked the story also felt good kept me entertained and i mean anytime to be a shining knight in armor is fun. I'm not much in to RTS's but it didn't really feel like one because in the end it all came down to your one guy, the fights were fun but a little challenging I have to say teleport was the best thing ever XD. One thing that irritated me was i couldn't use Obliterate on reapers, siege weapons or the Lord of War, i made it through the game on first try only came close to losing on the last fight.
Over all if it was a full length game i would consider buying it but i guess even when the bigger game comes out its still a flash game not going to be a full fledged game you'd buy at a store i guess so we'll see what happens after that. But great work can't wait for Ortus.
