I just found a glitch on the boss of Deep space stage 2. I killed just as it began to start shooting, and the boss is simply floating around, not shooting any bullets now, and the stage will not end.
I'm not sure if this is a glitch, but if you put an auto-reload mod into a rifle, you can no longer reload the weapon manually, you HAVE to wait for the auto-reload mod to kick in and start reloading it. In other words, don't use an auto-reload mod.
Peater, It works just fine on a laptop, I've completed all but 23 and 25 on my laptop so far. As for macs... too bad, macs suck anyways, get a windows PC.
While flying through space blowing stuff up is all good fun, this doesn't seem like a very great game to me. First of all, it's too easy. Second, I find it really annoying how you need to re-purchase items that you have already bought whenever you get a new ship. Why couldn't you just move the items to your new ship?
Well, i've completed the game, gotten all weapons and stats to 99, but I still dont have the excalibur gatling gun...How do I unlock it? Also, how do I get the last 2 achievements?
Multiple magnets do help, yes. If you have 4 magnets at level 5, you can just sit in the middle and every coin will come right to you (provided you have enough missile launchers to kill everything).
I only have one problem with this game. During some of the boss battles, the bosses have very sudden attacks that have no indicator that they are about to happens, and thusly can be unavoidable depending on where you are. You should add a short time before the boss' laser attacks where it charges up so that the player has a chance to dodge it. Very annoying when the boss just instantly swipes the area with a laser.
just died on 71. Easy, no cheats/hacks. (i've got all 3 badges already so I play on easy and get as high as I can). Used 4 rockets, 1 signal booster, then covered the map in blade shooters. Used monkey storms to stay alive when bloons reached the end.
For those complaining about the being a guitar hero clone or w/e, its more like a clone of DDR or Stepmania. Guitar hero uses a button hold + strum system. This gmae is pretty much a copy of ddr or stepmania where 4 possible notes come and you only have to tap them.
