@ xo_leathermouth : I literally just beat it. I moved Odin to the plateau to the middle-right side of the map. I then built two mortars where I saw where the Creeper would start to pile up. I also built a blaster on that top ledge (where the natural bottleneck is) so that I could fill in that canyon with collectors and reactors. I put up SAMs just after finishing the mortars and blaster. Good luck!
I have always enjoyed your Bubble Tank games, HeroInteractive. I anticipated Bubble Tanks 2 after 1, and was very pleasantly surprised to find Bubble Tanks 3. You have really outdone yourself, and your team. 5/5. One thought I had to add to the game is a flag (coloring, really) to a bubble field that you have visited but not completed. I find myself running from big baddies to chase lesser foes, gain power, and then not remember which field it was that I originally ran from. Not that it matters, in a universe of infinite baddies. I'm just a perfectionist, and it would bother me if I ran from a bubble field without finishing it >.<
Is anyone else having problems with mission 2-4? Not that it was too hard; but rather, it is too easy. I'm sure I would have gotten all my freezes after a long period of time, but I don't feel like waiting around for an hour to do so. I reset my skill points to just have the bonus freeze chance. I'd just like to make sure that I'mnotdoingitwrong lul.
Out of several thoughts about this game, three come out to the top: adding a save feature, changing the darned color of the enemy's projectiles (I usually try to shoot or dodge my own seekers), and add a "Reset Upgrade Path" feature so that I can go back one upgrade if I made the wrong choice of upgrade path, instead of just restarting all over again. 5/5 even without that stuff.
The game was great. Fine graphics, funny notes (for a scientist) in the background, and overall good gameplay. Controls were easy. 4/5. It could have gotten a tad bit more challenging at a faster rate, but I'm not complaining. I'd also like to mention that games like these do not take into account the force of kinetic friction (i.e. the black rubber piece, although moving slowly, was able to push the nut all the way across a board), but that's not your fault, and I will not blame you for it. =]
A good thing that you might want to consider adding is a pop-up box that allows us to see what we get when we upgrade a tower. Overall a very good concept, and I hope to see the full version!
