Are you sure your not just playing a mode that doesn't let you go in certain directions? Perhaps try closing some of the more memory hog tabs (facebook, etc.)
A valid option we took in consideration.
Unfortunately Flash sometimes do not read the hold mouse input (maybe even for an instantaneous moment, but it happens) so it could work not properly.
closest I got was 599 seconds, 5 tries later I couldn't get more... I timed the last time with my system clock, 12 minutes and the game said 561 seconds... so I wasted more than an hour on this silly game and badge, juggling the big asteroid until it somehow managed to get more speed than I could repel. And the timer in the game seems to be broken (12 minutes > 561 seconds)... ffs...
Camera angle is just awful, you need to memorize the track if you want to win (at least last track). Also, it looks like the same physics that applies to you doesn't apply to your opponents; they don't skid or swerve at all and they can pull off some sharp turns that would leave you skidding into the wall. And even with everything maxed out they will often come from nowhere (so far behind you can't even see them) and fishtail you in a sharp turn, causing you to spin out of control and letting everyone overtake you. 2/5
getting white screen too... so wait, the only solution is to delete the save game? when I've finished the game, already been grinding for days, bought the last plane and all the slots... ffs...
ok, I managed to beat the final boss somehow... but beating lvl 10 boss without taking any hits? even after 50 attempts I can't seem to do it...
oh, also, don't even bother with the final boss without ALL the upgrades... and that will take some grinding. Lvl 13 with fully upgraded lasers is best for grinding, 300k each run.
at first I thought it was a really bad version of Canabalt... then it was like playing an old arcade with the right arrow broken but pressed down. Then I realized this is almost a ripoff of a really old game called city jumper. But city jumper was way more fun, and it didn't lag. In the end, bonus level 3 reminded me a lot of Copter, another golden oldie... So yeah, even though this game sucks big time, at least it evoked some fond memories :D
