So good, I called in sick to work once to play it!
Wow! I have put in many hours playing this game, and learning how to get far in it. As everyone has already said by now, the health of the ants at the upper levels (50+) is ridiculous! The money you get is nowhere equal to the amount of effort put in to kill each one. I signed up for Newgrounds membership just to comment on this game, and to share how it is possible to get a 19,285 score. A lot of people call "hacker" or "cheat" on a score like this, but it IS possible. Hint - The impact cannons in a ring around the anthill will give you a lot of punch for the dollar. Match that with ice towers behind, to slow the critters, and you stand a chance! I think I was at 5 of those full-bore Impact Cannon's, 2 ice towers, and a maxed out missile tower in the back to catch stragglers. I eventually I lost due to the ants charging right through anyway, with about 3200 life points! Still, I was impressed with how well the fortifications of just Impact Cannons held up. Great game, and it deserves many sequels. The only thing standing in the way between greatness and what it is now is a tweaking of how the ants grow in power, and how the money is make. As the title says, I took off work one day just to master this game. Amazing, since the only other time I've done that was Grand Tourismo 4 when it came out.
