Hints (real) I HAVE THE GAME
For every level there is no time limit to get a star. For some stars there is a time limit (such as speedy comets and purple coin comets). When you play with p2 you don't have to hold down B to collect star bits. B, for both players is shooting star bits. When you hold down A for p2 you get a circle around the pointer. That is for stunning enemys but it won't work for all enemys. Also, there are several different power ups. One more thing, thankfully for each stage u don't need 100 regular coins but for purple comets u need to collect 100 purple coins within a time limit.
White: turns you into a ghost (touch light to turn back)
Black and yellow:turns you into a bee (touch water to turn back)
Silver: turns you into spring mario (get hit by an enemy I think to turn back also you can press A to jump really high.
Rainbow Star: turns you invincible for a short time.
Red Star: to get this star you must unlock it. You can only use it on the observatory grounds. (enables you to fly)
Fire flower: you can find this star in stages it will allow you to throw fireballs
That is all for now
