Yesterday, I was creating my rom and everything worked fine..until I test it, it crash.

1. Can a level crash because of another level?

2. What can possibly crash a level? it crash when I have added coins, but it's maybe not because of it.

3. I can see all the level path on the bottom screen,even if haven't unlock level

1. Not possible; other levels have nothing to do with a level crashing

2. Check your sprite sets, you may be using an enemy object or something that doesn't exist in the current sprite set

3. Not sure about this one
