hey there! thanks so much for the feedback, actually didnt expect someone to try it so fast :D yeah, really need to make a tutorial. you can do a fliptrick with spacebar when you're in mid-air and a grab-trick with holding E, also while in mid-air.
Basically the idea is: you can build a puzzle-park in the park editor, set the goals in terms of the number of tricks you should do before reaching the finish line and the amount of pushes available to you, finish the puzzle and upload it for others to play. so feel free to build one :)
might do some quality of life updates soon(ish)
