I left an earlier comment saying the sky gave me a headache - I've now tried the game now that the developer has changed the sky from purple static to something more calm (gradient sky with particles).
I really want to say thanks for this change: turns out this is a really relaxing game. It's gone from being a hypothetical like to something I really enjoy playing.
Though, the teacher gave me an F and I had to redo an assignment :(
Thanks for making the update! :D
