The only real bug I came across was the one Jack pointed out, It looks like when the bullets spawn the collision pushes them out of the turret sideways, so whilst the turret is aiming at the enemy, the bullet misses and it just sits there firing endlessly.
I also would have preferred a higher camera angle but that’s a personal preference for more easy selection of tiles.
All said and done though, a fun little game, I enjoyed the chaos as the tanks show up and everything starts firing wildly at each other. Could be a really fun little tower-defense game with some further development.
Great job.
