Thank you for the feedback! Don't worry the big circular room was the end of the prototype. Though I understand why you weren't able to progress as you would need to increase/decrease the distance of the box you are holding, which is the scrollwheel or if you are using the laptop pad is o/p. I fail to mention that control in the tutorial stage so that is my fault, which I will definitely be adding along with other changes. Im sorry you found the energy rechargde confusing. I have heard it is confusing the first time, the Energy Boxes (the purple ones) are static but can take and give our its energy. It is used basically as a sponge so that you can shrink or grow the blue boxes more when your gun is full. I don't know if that helps explain it any more, but I will think on possible alterations that could be made to the mechanic. And thank you for playing!
