I loveeee games like this! It took a little bit of adjustment to figure out the timing - does it take longer to loop if you put more buttons, and then shorter time to loop if you put less? That's what it seemed to be for me, which is fine but I think if you continue the game you should put a visual indicator of how fast the actions are looping through (like each button glowing after the next). It was very satisfying to make it through the levels, though, and great job!!
