Thanks, I was able to play it now! Had some fun with this short puzzler, though it was a bit easy and I wish more time travel was in the demo though :)
One suggestion I have is to let the player dash - since there is a lot of moving around and going back places due to it's puzzle nature, being able to move quickly would be very nice. And one bug I found, when finding the switches in the flowers, it left behind an invisible impassable tiles.
Good job overall, I hope you continue to work on and improve your craft!
