Best game ever except for one Thing

This game is absolutely amazing, the music makes the game very foreboding and the gameplay is absolutely stellar. At first I thought I would hate it since it was based on Oregon trail but I absolutely love it to death and beyond. There is just one problem though. And no it is not the fact that I had to pay for expansions or that the game was 3 dollars. Its the fact that clements quest seems to have a problem when I cant get past the giant mountain after Las Vegas. For some reason I always slow down to a crawl when I get to the mountain and I dont know how to go faster. I have seen youtubers play it and they go over the mountain like its cake walk. I would like and update where it is not hard to accelerate to top speed on any incline, or at least a way to go faster. The game is stellar but clements quest needs to be fixed, sooner rather than later. Other than that the game is well made and I am just addicted to it. Thanks for all your work so far.
