I found a bug that can't quit normally.

When I was playing the second level, I entered from below, didn't eat the digital cube, and repeatedly groped for the method of jumping to eat the digital cube on the stairs. The result was not successful, so I gave up, moved on, went up, and met the hurdle that I couldn't jump. In the process of groping for props, I killed my only three avatars, emmm, and then the game didn't start again, but stopped there, although it only appeared once, behind. The later reappearance didn't succeed, but I think there must be a hidden bug at large.
