Probably, I should've treated CTRL as a slow-mo button, because it is its purpose. The whole idea was born because of the "CTRL" button, so I wanted to use it anyways. I see where you are coming from and agree that the execution wasn't the best, and I will make a better control (so that CTRL won't feel as a redundant button).
But I'm happy to read that you liked the game. And I highly appreciate the comment, it means a lot for improving my skills and the game itself!
