Fun game, will be playing this one a bit more, definitely reminds me of the games you listed (Gauntlet meets Smash TV, with the new twist on games where you can purchase powerups in between rounds). Love it so far.
Qahrahm: In the unlockables section, there are 2 things that should unlock to help you find all the planets. This first is a sort of checklist to see each round and how many you've found out of each round (ie. You've found x/y in round 1). The other is the option to show visited planets. It places a check on each planet you've "visited" as you got thru the rounds. Hope that helps out. If you don't have those unlockables yet, keep working on other achievements until you unlock those. Good luck. :)
Great game, one of my favorites. I've experienced the issue with the sun seeming to be much stronger than a planet that has larger mass, but other than a few oddities, the game still is great. A few minor tweaks, and in my opinion could be a near perfect game. Great job, and thanks.
By far one of the best flash games ever. Excellent job on the game, the graphics, the sound effects, and just the overall interest.
I'm not great at the game, but it's definitely one of my favorites. Thanks for the hard work and dedication.
