Thanks for the comment, sorry to hear about the problem. You do jump, but in the further part of the game, when you get to go under the water.
As for the trash - you need to gather all near the beach. When you go to the dumpster it will tell you that you have to gather trash and if it does not that means you started the next night. On the third night there is a car and you just have to examine that and then go to sleep as it says in the game itself.
