I read the document folder that comes with the nexuiz 2.5.zip that i have to have the jump button pressed before/while touching the ground to gain a bit of speed - ok doing this. I am using the laser to jump and in the air i get about 80km/h but as soon as i am touching the ground i am slowing down. I tried to run backwards and using the laser to push me forward while having the moveback button pressed but it did not really work as i don't see where i am going this way and i don't gain speed continously. Do i have to go over the pipes? Don't really think so...
Another problem is that as far as following the docs i should only keep the forward button pressed while jumping (pressing the jump button before hitting the ground) but what should i do with the laser? I also tried the mortar which is found behind the first time starting of this map but i rather blow myself up than speed up.

Also i can't stay on the "road" and touching the sides on this map means loosing speed as far as i found out. I read that i can control my movement in midair if i let the forward button go and am steering my jump with the side buttons but i still can't really stay on the track.
My best time on level 27 was 41 seconds and i can't beat it so help is very appreciated.
