Amazing!
I was very, very impressed by this. I especially loved the ability to "Skip" the first little bit to get to the menu, and then the ability to skip the intro to the game as well.
Everything looks great. It's very eye-appealing.
The difficulty increase is well-balanced.
The only complaint I actually can make about this is that oftentimes I couldn't see around the ship, so I'd get shot without knowing there was a blast coming...but that happens in many third person games, so it's not a worry at all.
Ultimately this deserves a 5/5, 10/10 in my opinion...excellent Flash.
I'm curious...how long (Just take a guess in number of hours) did this take for you to make?
