I kept hoping there would be more involved, like a boss level or something but it was the same waves over and over.
I didnt even realize I could change the "turret" until I read the instructions but I didnt feel as though it was necessary to even have the function considering it was doing just fine being forward.
I wasnt too fond of the controlling either. :(
Music is solid and the graphics are cool too. I did end up playing it for a while. Nice job.
