This game was pretty fun! I really enjoyed the seamless level design; it gave the levels a kind of portal-style puzzle aspect.
One thing I did have a bit of difficulty with was movement/glitching, I didn't find any difficulty in the tank relative movement itself, but during tense battle moments, lining up the tank perpendicular to the wall was a bit difficult.
The special power-ups were super fun to use as well.
Overall, a very fun and well-designed game!
