Great start. I like the multiple camera angles. The missle seems to have inconsistant targeting and I never had a graphic where I bought the missle turret. Once monsters got to my base they just stood there and drained my base. (probably attacking it but looked funny) The upgrade value of the first turret was very poor, cost more than 3x the purchase price and added 7 damage. The speed is a little slow even on fast forward. There needs to be better firing graphics, whether it is a burst from the end of the gun, a bullet trail or some other effect. The enemy ships could use a little more detail, they feel a little too "sprite like". These comments are intended to help you improve the game, as I would like to play again once updated. 3/5 for first attempt, 1/5 over all completeness.
the final ship is not worth it. The 4 gun ports look appealling, but the 4th one costs 100k... that is money I should have put to upgrading the weapon.
I was very upset to see I do not earn the corruptor distruptor badge just because I am on medium and not beginner difficulty. I certinly would not have kept playing if I would have noticed that.
Fantastic game like always, 5/5 for Bubble Tanks! The one thing players never seem to understand is bigger IS NOT better. The tank I used to finished the game was nothing more than 3 laser beams and radar. Smaller = avoidance, WOW whatta concept!
