It took me a while to know how to move the first window. I didn't realize that pausing was a crucial mechanic here. When I did get it, it was quite fun. I like how there are different approaches to solving the levels and you don't always have to use your time powers.
The sfx and music were really solid. Unfortunately the movement was difficult to work with. You accelerate to full speed in less than a milisecond. That led to my death far to many times. That's why I wasn't able to finish the game, so that's unfortunate.
Nonetheles I really liked your game!
