The rewinding & clone system felt a bit confusing, i literally couldn't get passed level 4 LOL i got confused with the clones and couldnt figure out how to do it. There is a lot of potential here but i think you need to get some friends to playtest and give you feedback in realtime so you can see how a common person would understand the game's mechanics.
anyways, graphics audio and voice lines are great. if you have lava beneath the platforms then you should let the player be able to fall into it and die, thats the first thing i tested lol if i can fall to the lava :D
good job friened and goodluck
