I really love the style of the game, it reminds me of the kind of cartoon-styled games you would see during the Flash-era of web games.
Unfortunately, I couldn't figure out how to get past the area that requires holding down the jump button and reversing time, even after looking at the instructions on the io page. During that section, I was attempting to hold down the spacebar and wait for my past-self to get near the platform before reversing time to that spot, but that didn't seem to work. I also tried hitting space right after reversing time expecting it work like a double jump, but that didn't work either.
This really saddens me because the controls felt SO smooth for a platformer game. It also felt satisfying to reverse back in time during that part where you have to press the button and go back to the previous spot; I was really craving for more of that kind of gameplay.
Perhaps if the controls for the time reverse jumping thing were simplified in a way, it would be much more accessible for players who are just starting the game instead of immediately beginning with something so complex.
