"Expensive" achievements are bugged (I never get the money from them--not sure about the shop prices that are supposed to be reduced, but I think they may be too).
Fun game! It makes absolutely no sense (hardware can't attack software), but I guess neither do floating blocks or shooting swords. Fix the repairs and it will be awesome.
Astronaut 1: Obama cut our funding! What do we do?
Astronaut 2: Instead of hiring the best scientists and building the best rockets, we'll just do trial-and-error, collect the money and oil polluting the air, and slowly make better and better rockets out of the wrecked pieces each time it fails!
Astronaut 1: Wut?
The artificial stupidity needs to be fixed, and an upgrade for money to last longer on the field would be nice. 3/5, but would be a 4/5 or 5/5 if this was fixed.
@TheExhale--Actually, it's kinda cool that they offer a temporary form of the premium upgrades. Very few games do that. Premium content almost always implies a permanent paid upgrade. It is cool that they offer a free version.
@GigaSojan I'm guessing the heroes aren't worth it until late-game or if you have premium and are starting new. I have premium and started over with heroes, and they are awesome!
All levels are doable, but some are just too hard to actually enjoy unless you are obsessive compulsive or just straight up awesome at control (the shrooms level for example). Kinda reminds me of Sector Z.
It would have gotten a 5, but the sea snake doesn't make sense (it's too much luck on where it generates), and so I unlocked the levels and got over 50 on Passage but I'm not getting the hard badge. Hmm...

Did you do it via the cheap unlock in the options menu. You were warned twice that it locks out badges.
