Nice game, good work! I really like the ghost form mechanic, awesome idea! However, I felt like the attack could be faster, the recoil time is a little long. And/or if attacks would push back the enemies it would make attacking a little better, because right now it is almost guarantied that you get damaged when trying to hit enemies coming right in your direction. But it is true, if you would not get damaged, then there would be no point in the ghost mechanic. I had fun playing your game, congratulations! :)
