Hello, just a quick question.
I saw in a tutorial that i need long reaction time, what exactly does that?

Well the reactiontime is the time given by the game before the next frames start. I mean you saw in multiplayer you have a timer, if the reactiontime is very high like let's say 200+ it will be moving very slow and you will have some time to move your tori and think a tactic, if it is low like 20 or lower it will be moving very fast and u have little time to think about your moves and etc.

This is reactiontime.
