I'm interested in doing a run at some point and getting in on some Micro Maniacs hype.

Wondering if there should be some clarification on rules regarding persistance & power up levels.

Should you be limited to starting ordinary challenge runs with 2/2 power or is 4/4 also ok? The most recent runs do start with some power already unlocked, though from skim watching don't think the extra power was ever utilised anyway.

Similar question to unlocking one of the 4 characters and using those, assuming you can unlock the characters without blocking access to "mice n easy"; are any of those allowed and/or even relevant?

Does anyone know if any characters are faster than others? Was thinking of using V4, pyra seems to be used in challenge runs; looks roughly same speed to me so guess personal preference. I only remember Waldo feeling slower, but could be wrong.

Also I'm guessing it's possible to do a challenge run followed by an all challenge tracks run in the same session, unless I'm missing something?
