Ah, time running out should have brought you back to the menu. I may have accidently commented out the code haha.
The forest was intended to slow the frog down by half speed (but does not). You can complete the track in the given 60 seconds with the drift mechanic, but it is a poor implementation of drift, so it is a little tough to figure out when to drift/release/etc.
Thank you for playing and for the feedback!
