Entire story is lol. My small sister started playing SP and completed 20+ missions until first race mission. Goal is lap in 33.3s. She tried may times and done record ~110s. So I tried myself and woo new record ~100s. But goal is 33.3s. Maybe this is bug wrong number set as goal or I do not understand something? I done only straferunning and rocket jumping with that basic gun.

i really have to play the single player
i wonder why so many people have got a problem there

edit:
1st try: excatly 29 sec.

You can complete with laser (1st gun) too. Yeah, this mission is pretty hard for 1st timers. Time was increased in svn.

Suggestions: change angles when shooting, check which gives you most push forward and not upwards. Also there is a jump pad at the end, which accelerates you.
