Seems like a pretty cool concept. Couldn't really figure out how to spend the 10 coins to get the laser colors, though.

It seems pretty intermittent, I've had the same issue as you and sometimes it works and grants you new colours
It should just do a check if you have the correct amount of coins, it won't subtract them and the colour should just get added to the wheel. But honestly, no idea why it's not working 100% of the time
Thanks for playing!
