First Playable (Kinda)

 This week we were tasked with taking our prototype and taking it to the first playable stage, while I still had not resolved my issue from last week (namely my car simply refuses to jump) I decided to go ahead and flesh out the Test Level I had made, deleting the planes I was using as roads and replacing them with solid cube platforms, floating in space above a makeshift death plane. I edited some values to make my car more comfortable to control, added some scenarios that I could use to test the car and implemented a ramp from last week too... Then it came to the car. The test is playable if not just barely, the big problem simply being, the car jumps once... and then never again. Still. I have talked to my lecturer, made countless search's on the internet, straight up replaced the code in some scenario's but to no avail, the car refuses to work. Hopefully this problem is resolved before next week as I cannot really progress in the creation of my platformer without the ability to jump from platform to platform, below is a picture of what the current state of the game looks like, I hope for it to make some improvements very very soon.
