Thanks for playing, you can spin and manipulate the spinner as much as you want during the first couple of seconds where it's unlocked. More spins means you get more power but you can still grab the spinner mid spin and pick a colour it locks into.
A good stratergy is to spin it once it unlocks and look at the enemy spinner to see where it might be slowing down then grabbing your own spinner and trying to place it on the right colour. Timing can be a bit tight, but I found when I made it too lenient the gameplay became very trivial.
I'm not sure how much more I'd expand on this idea, i'll likely do a post jam update just to clean some things up though.
