Random effects on a looping platformer may not be a good idea as it increases the playtime in the initial area, especially when the randomness increases the chance of death instead of the other way round, it ruins the effort of practice and the confidence players had built up.
People usually get interested when they explore new areas or experience changes when looping back to the same area. There has to be a solid reason for players to loop through their playing process and not get bored, right?
The weird and sudden camera movement appears when jumping from spawning point to the first platform. The art style is very consistent and polished.
