Hey! I remember playing your game from the BlackThornProd game jam, it's cool to see how much you've improved in a short amount of time. This game was really fun, the mechanic was unique and the puzzles were fun. The tutorial was a very nice addition.
I did happen upon a glitch where it said I had more clones then existed and I was able to delete the player character.
If you wanted to improve, I suggest adding some additional particle fx for when a clone is deleted or when the character is moving around.
Overall, fun game! Check out mine if you get a chance!
