Gravity Flock it was good.
but here are some tips that would make this game GREAT!
1.add music.
2.add sum kinda upgrading sytem to the game.like higher gravity upgrades and such.
3.everytime u upgrade the star, it gets bigger an brighter.
4.make the planets look like planets not just bunch small an big yellowish dots.(earth like planet,mars looking planet,venus, jupiter ect)u get the idea..
5.add sum sandbox thing or sumthin like -darktyreal- said.
6.u could prolly add sumthin like on one of the higher levels of the game where on at least one of the planets theres a colony that recognizes ur dangerous star an they try to destroy it.it could like like tiny dot sized ship for all i care.it would make the game look wicked awsome..
well i loved this game but what those suggestions i placed for you would make i game that i would really pay a couple bucks for to play =] good work though
