Hey Timmy, good map I enjoyed it (though I do play on an anonymous account so I am the yellow and black guy), it was hard to do but I eventually found a trick to getting the weirdly positioned checkpoint, was this (checkpoint) on purpose or no?
sorry about my goofy writing I generally write these at 3am (and this is not an exception😅), I see that so far you haven't beaten it (officially at least) so I thought I might at least reveal my secrets I would suggest after getting to the pipe going about 1.1 line spacings from the edge then flooring it you should reach a speed of 110-116 km/h before jumping and then if you are straight and in the right place then you should land half your car on the checkpoint and bounce backwards into it, after this, you should be able to go back up the pipe, from there turn around and follow the line on the leftsayt on that line and you should land on the ending parts
