I can reach meta-energy activation faster if I actually DO NOT upgrade density and gravity, instead keep the meta energy unspent. The bonus from unspent meta-energy is much better than upgrading density. What kind of game mechanics is that??!??
Definitely a bug. I'm not sure why this is happening, it only seems to be happening to a select few. Is your Flash Player able to save enough data? Right click the game, go to settings and then click the tab that has a folder icon on it. See if the data allowed to be saved is at least 1 MB. Our game saves a ton of data and it's possible that some settings might be restricting it from being saved properly.
There's a glitch in the game. If the troops start hitting a building, they keep doing it even if the building spawns troops, so they keep hitting the walls while the rats are eating them alive. That must be changed ASAP. Otherwise, good game.
My personal best: 40675 in survival mode. Starting like 25k, the screen gets more and more cluttered and one needs a pretty powerful computer to play. From 30k and beyond it's just pure luck. Bosses after bosses after bosses. You don't finish killing 3 bosses at once, 3 more show up.
Fun game though. Tesla gun is invaluable. ;)
