First impression: It would be more convenient if I didn't need to install it. Is there a way to run this game without an installer?

A simple but interesting premise. The core mechanic of stopping in mid-air to form platforms is new to me, and you use it well. The different colours for each instance of yourself make it clear what is going on. The movement feels responsive and fast, but your past selves are very thin platforms and it's easy to accidentally walk off them. The jump arc is a bit odd, until I was used to it I couldn't jump with any precision.

I liked how the game always gave me one or two more time-travels than was strictly necessary to solve the puzzle. It made it possible to recover from mistakes without starting the level over. That's good puzzle design, well done.
