Demo questions/problems

[Q]

Thank you for the quick reply Phoenix_D

1.) No, the speed meter is not red.
2.) It is difficult to buy new engines at the beginning without credits. And the failed missions costs you even fines.

Is is possible to change the values for the time limits in the demo?
Do the cheat codes work in the demo?? I tried it without success but on my european keyboard I have to use the "Alt Gr" key to produce the "~" and therefore I am not sure if this was the problem
