The game can be interpreted very deeply on philosophical level. Loved that about it!!
It would have been interesting to see how the gameplay would have changed, if you went crazy with the idea of your past selves helping you.
For example, say you need to fly to a platform and you can jump once. But can you let your past selves stack on each other and then climb. idk, just thinking of random ideas xD
But all in all, such a nice game! Loved it!
