Fristly, good job on your first completed game!! :)
The sound when holding down the pewpew button sounded like I was shooting stuff inside a reverberating tin can :D It's kinda funny that the sound will stop you from doing the thing that is probably the most effective at deleting those enemies!
Really enjoyed to be able to go sideways in this, didnt quite feel like i was moving with a tank, but with the right visual/animation, you could totally sell this movement.
