I wish I could beat entire game, but after getting to last part of level 2 several times and dying on the stickies I just ragequited :P
Gameplay:
It's a great mechanic, puzzles are interesting and movement is really good, but there need to be some kind of a checkpoint system, because some people will just ragequit on that game like me :P
Audio:
Music really fits and is calming. Sounds are also well made, but they were a bit too loud for me (just my personal preference).
Graphics:
I'm honestly in love with the font you picked, it's amazing. Sprites are well made, but I couldn't feel that everything was a whole. It's good to choose a color pallet (https://color.adobe.com/pl/create) for your game and try to paint everything with chosen colors, same for style you follow. Then your game would look like a whole ;) Take HyperLight Drifter as an example, it uses only several colors, but it gives the game a lot of life and make everything easy to understand.
Innovation:
The mechanic is really creative and it's totally different from Braid one, so I really respect it ;) Tho game is really brutal considering that many of 'Me' from the past died for my sake.
Theme:
I certainly can see the leap reference, however I got a bit of a problem with bounds. I know that there are platforms/walls that block us, but it isn't enough for me xD
Overally a great game and good job for a week work ;)
