Pretty exciting.
The graphics were pretty good i loved the explosion but i disliked the background.
The controls were pretty basic but yo need to make it more obvious if the turrets facing backwards or frwards can get confusing. I loved the sound and explosions.
My only suggestions are change up the backgrounds,bigger better tanks,owerups where you can inflict more damage,and there was a glitch when i died the barrier(that you can't destroy) disappeared i could still shoot at it but it wasn't there,
