nice game, but i think it would be better if you gave us some solid numbers for the items&skills. I don't even know how much hp I have or how much max energy I have!
is there a level after lvl 12? because if it's not, I'm not getting the achievement for beating all normal levels, and if there is, it would be nice to give a heads up.
where the scorcher doesn't work, try spamming drones. with all 5 upgrades, you'll start gaining money at a ridiculous speed and you can spam other towers when you feel like it.
the trick is not to have a few super long elevators, but to have a lot of shorter length elevators. (be careful not to connect them. if you do, the combined elevator will only have one elevator cabin)
whoa, enemies just refusing to drop dead even with upgraded gatling and ship cannon! for those of you having trouble with the game, buy the jetpack and try out the ground mines. granted you can afford it, ground mines are the best solution to tougher enemies (bosses too!)
