Indeed it was the plan but I did not have the time to implement it.
There are bugs generated on 10 elements : sky, clouds, entry wall, end wall, holes, ennemies, platforms, coins, sfx and music.
Each element can be low-bugged, medium-bugged, high-bugged or not bugged at all. Some high-bugged elements (1% probability) would have to crash the game and there you got to pass directly to the question. Else you could play the game 3 times.
The idea after is to do another level in a complete different form (in 3d for example, on a complete different theme,...) and to improve the game experience maybe not randoming the bugs, choosing the right combination.
