This is "Double Jump". The bonus goal is supposed to fall. Sorry for the extra work, but you have to delete the spring, make an exact dupicate (duplicate just the properties and optical length (not the true length of 1 meter)), and then you can play. Can you tell me how to fix this so you won't have to do further work on future levels? It always changes the length to 1 meter. Sorry if you can't understand, I tried to make it as simple as I could.

Oh yeah did I tell you that the next level will be a compition? Top 3 gets ribbons! It will be judged by me on complexity (60 pts.), design (5 pts.), and the "WOW!" factor(35 pts.). Total is 100 pts. Just a heads up.
