Thanks for the feedback! I'm not sure to understand the problem that you mentioned. You're activating the power that is stored at the bottom of the screen. And you can store only one at a time.
Now that you explained it, I get it. But I didn't when I was focused on playing XD
As often, what seem obvious for the dev is maybe not for the players. In 3 hours, there is no time for QA testing and ergonomic checks. XD
