Really glad you're continuing development. It's a great game! I'd probably go for option 1 but I'd also like to see something that's about being "King of the Kill" with online leader boards.
The person with the fastest time to the summit could leave their name and a message there. People would then climb up and kill that King of the Hill and if anyone gets a faster time then they get to be King of the Hill.
To prevent one person from being King of the Hill forever you could alter the layout each week/month and the person who was King of the Hill for the retired course could be added to a Hall of Fame. (There's a racing game called Vecter that has a good implementation of this).
Keep up the great work! :)
