When I’m trying to open it, it says that icytower15.exe has stopped working. I don’t know why because I was playing it normally and when I closed and re-opened it, Windows says it has stopped working.
why does the charecter go slow when i jump and how do i fix it?
Does it always stop at the same part? What other things where you doing?
Try backing up your saved games and re-installing the game and restoring your saved games to the new installation. It is possible some files went missing or weren't installed propperly the first time and that is what is causing the problem.
