Would've been alright if the handling was a whole lot better. Honestly if you made the guy move in a grid kinda like trapped I would've been completely fine with it.
Needs clearer instructions as "red star" and "blue star" aren't on the first screen and i had to play a bit to figure out I could move to a different screen. Major problem was that the bullets and enemies don't get penalty for touching you, which means they'll infinitely collide with you until you're able to move out of the way. This causes your health to drain every time you're hit.
