One of the most enjoyable in the jam that I have played so far. Such a great experience with the smooth movement + clones of myself! Everything feels really well made.
One thing I really liked was how this game is still running smooth even after so many deaths. I don't know how you did it, but you did it really well. The gameplay core is a simple mechanic expanded so well---in the end, I actually enjoyed watching my past self suffer in the parkour than actually attempting it myself haha. (I have failed countlessly at one of the jumps it is hilarious)
One small suggestion is probably to make the clones half invisible---to not hinder the view of the player. In my gameplay, although it is really silly seeing all the clones of me running in front of me, it distracted me from planning my next jump in a game with such fast pace.
Great job!
