Impressive work! I love the BatRang like mechanic from Arkham City and I think it is cool to have made a game centered on that!
I couldn't kill the ennemies however and since the boomerang is slightly on the side It was a bit hard to aim.
I also felt a bit lost but this made room for exploration and I like that!
This game shows how much can be done in only one week and I will definitely bring it up to motivate some of my friends ;)
