I REMEMBER THIS GAME!
i think i found it on addicting games.... anyways... after the first time i played, i ocuildn't rember the name.... and thus, couldn't find it!
i guess now that i think about it.... all powerups are temporary!
but the bubble powerups will last untill you fly your ship overthem, which is when they will be used... bubble powerups have pictures inside of them so you know what they do...
