You made this in a day?! I never would have thought of something like this, the only things that I could say that needs to be improved on are that they were no clear indication that you could double jump, and that on the last level, it was hard to see the unreal world, which led to a couple of unfair deaths. This is still really impressive that you made this in a day, and it's good that you're starting game dev at the age you are now, I can imagine you making a game like Celeste in a couple of years time!
Knowing that you made this in a week is really impressive, the art and sound design is beautiful, it's a relaxing game. The only bad thing I could say is that we have no clear indication of when the platforms are going to go invisible, and this is especially annoying when it comes to the moving platforms. Other than that, that's it, I'm looking forward to see what you come up with next!
This game really reminded me of There Is No Game. It might be a bug, but having you download an HTML file to play in your browser added somewhat to the immersion. The only bad thing I could say is that there is no clear indication, in the beginning, you have to press enter, other than that, that's it. It's impressive that you were able to make this in a week, great job!
