The art is really cool, the sound is good but repetitive(it's okay, I'm also no music master) and the idea is really cool, infinite runner with rewind function is actually original(never saw anything like it) but the problem is that the game is too hard(It's also okay, challenging) but the rewinding mechanic is not very effective because you rewind everything so it doesn't change too much. Maybe if you rewind only the platforms moving and keep the player still it would be funnier. But it's still a great game! I liked it!
Hey, test mine if you want. I bet you would like it!
