Hey I loved what you managed to do with the art pack, Really creative. It reminded me of star fox on the snes.
It would have been cool to have some more enemy variants then lead up to the one we saw in the game.
I had one small bug my mouse pointer would go off the screen when the in game aim was over the boss and when i click the shoot the game would minimise. I think this is a really easy fix, No big deal.
