Double MG, Shield Gun, Damage Buff, and Missile (where needed) makes this pretty easy. For the hard campaign, I ended up using two Damage Buffers (in 1-2), two Shield Guns (in 3-4) protect Buffs, and Double MG (in 5) - made it *very* easy once I got the MG up to 6 damage (combined buff 85%+, MG Damage +2).
Decent game but the tactic *always* appears to be buy a MG, save points, and increase damage (nothing else comes close to doubling damage for 10 upgrade points).
Fun game early on but gets too hard too fast. Plus it repeatedly refuses to recognize my "x4 multiplier" (I've finished level 10 at least 4 times now with a max multiplier of x5 (can't quite get x6) including finishing level 10 itself with a x5).
Fairly fun game but I only gave it 2/5 due to bugs (worst being inability to get cursor to bottom of screen sometimes) and the *really* annoying Adventure Quest ads interspersed throughout.
Good game but the "finish random size X game in Y time" badges have nothing to do with skill. It is 100% luck - there's no time to strategize or correct going down the wrong path. Either you choose the right setup to start or you don't. Pointless.
This is by far the worst game I've played on Kongregate. Not only is it annoying and unfun but it is nearly impossible to successfully get a perfect due to flash lag/skips/quirks (and I'm playing on a very high end system).
