This is why I make games that only save between levels.
Challenging, original, good use of the theme.
When I first started the game, I thought, "There's no music? But then why is the 'audio playing' icon appearing on the tab?" But apparently there is music, and it's just so quiet that I can't hear it at all without turning my computer's volume up to near the maximum.
Is limited time to memorize stuff supposed to be part of the challenge? The fact that you wait a certain amount of time after the text disappears suggests maybe it is, except you can see everything while the text is still there.
