Rayman Pirate-Community

Could someone lead me onto the ricght track to start making Rayman 3 PC harder? I played this game so many times and i'm looking for ways to imcrease the difficulty a bit by:
- Removing Health (most obvious)
- Increase Enemy and Boss Health
- Increase Hoodlum Accuracy
- Increase rising lava speed?

Ideally you'd want more enemies, maybe even with different behavior, but I understand this is much more complicated than other, smaller changes and probably not feasible given the tools we have at the moment...
