So, as of right now, there are about 131 moves left until the event is over. So, if you're at stage 3, which requires 12 moves, and there's no increase in pieces past stage 5 (which is 16), it means you'd need 120 moves total to beat stage 10 without any mistakes. And that's absurd.
I mean, one move per hour, really? They should have made it 40 or 30 minutes to recharge, and without cap, so you could store like 40 moves and complete a few stages at once.
