I'm looking to build a stage with the right amount of jumps, platforms/structures hazards and slopes

I even also include Ladders to prevent jumps from time to time

thing is, i'm aiming this as a mdeium-size stage, so how many of each asect should i involve

note: a specific hazard i use often is the Spikes

the best thing to do is to use the stagestudio

agreed, but maybe i can assist with this

Sounds like an interesting idea, any picture concepts?

I don't understand what you mean by "perfect". Are you aiming to make the perfect stage for a certain character, or make one that's perfectly "neutral"? If you're trying at the latter (or even the former for that matter), a large amount of time and research is required.
