i love it, it has a mesmerizing appeal gained by the repetition and the good animation and song. ignore the haters, they are all smelly weeaboos. unlike me. I am a clean weeaboo.

i liked it, made me think of nu pogodi

i love this

it's sort of fun, but it's annoying that you make people restart with the mouse or space, you should just let people restart by pressing any key, or at least let people restart with the arrow keys.

i sorta like this, but it feels too slow for me to want to finish it. i think the problem with the "wall-climbing" is caused possibly by collision boxes of varying size. You could just keep the running collision box in the same place and with the same size as the walking one, and then that would maybe fix your problem. maybe i'm wrong and you already tried that, but if you didn't, maybe you should.

it was a bit too hard and the execution was a bit clunky, like the initially unclear rules, and moving platforms that don't function quite as expected. but i liked it for a bit. but when i got to the level where there were these new portals first introduced, i didn't see one of them until i accidentally fell into it! If something is important, it shouldn't be the same color as the background, so people can't see it. It should be bright and obvious, here even though the red portals aren't the same color, they're still dark so it adds unnecessary difficulty.

also, i got to the first red level, but then i got stuck on a corner and couldn't move anywhere or change the gravity, so that's where i have to quit. here's a screenshot of where i was stuck. http://imgur.com/a/Iaj6p

the thing that felt nicest wasn't the actual challenges, but the bouncy platforms, because the screenshake and little wobbliness made those feel nice to bounce on.

overall, it's an interesting idea and it's clear you put some thought and effort into it, but not quite enough for me to look past the flaws and start over from where it was broken.
