@Deathwalker14: There are some walkthroughs online to find all the letters if you just google them. The alternate ending is worth it. :)
@Tola: Wait, what?
Although it could use a little more polish (main menu, controls improvement) I genuinely really got into this game and really enjoyed it which is saying something. Certainly better than a LOT of games in the running for the Unity contest, I can definitely see this in the top 3. Great job!
@Zero52137 (and others): The creeps that split and go through your towers is NOT a glitch or bug. It was designed that way and it is a challenge you must face. The enemies can pass through any gap that is only 1 tile wide. Towers, being 2 tiles wide, are not passable. If you have two towers placed diagonally, there is a spot there they can split through. This can be good or bad for you depending how you design your layout. At any rate though, it is part of the game.
@JamesRevan: Despite the conviction of your multiple reviews, I would claim that your suggestion that the 3 developers who worked on Bubble Tanks Arenas for 6 months to produce "nothing new" is indeed false and call your abilities of observation into question. Although you clearly prefer BT2 to the other spin-offs (reasonable as some people like different things better than others), your claim that BTA and Bubble Tanks Tower Defense (BTTD) were failures and should not have been made is baseless and unfounded. Firstly, BTTD has received well over 20 million plays worldwide and a 4.26 which is pretty decent for Kongregate. Secondly, BTA is on that same track with, currently, a 4.17 rating and 1.2 million plays just after release. Still, I respect your 2 star vote regardless if your review is wildly off from the rest of the players.
That's not true codysaidhi. We have engineered ALL of the weapons so it is almost always better to have a 2 GP weapon than two separate 1 GP weapons. It's not just a matter of how many bullets you fire and how much damage they do, fire rate and strategic use are key factors in the equation.
In conclusion, I'd pick the two parallel over 2 basic cannons any day.
@Wolf3n: Those are life bubbles, not money bubbles. You'll get the same rewards regardless for completing an arena. Life bubbles are important, but missing one or two because it flies out of the bubblefield is not a big game changer.
Update: We're currently in the process of trying to fix the loading problem a few of you are experiencing. We thought we had it fixed- but alas... no. Expect a patch early tomorrow morning and please bear with us as we try to get this fixed.
This game is really not that hard guys. The key is to just relax and make sure you properly size your blasts. Click in the MIDDLE of a cluster and drag outwards and get everyone. That way you don't even need to shoot again. Also, be sure you get the majority of the ship in an explosion. Just nicking a tiny part won't do damage.
