Really well made game, the constant weapon switching and dodging the missile silos made it very fun to play. The upgrades were also cool and got me replaying a few times, never got stale. My best run was room 17, 572250pts. At that point the game spawned me in the middle of a giant mosh pit of tanks and i died like a second after loading in lol. Fun times!
encountered one bug where a large red tank spawned outside of the level, but the level still cleared without me needing to destroy it.
