Very clever idea! And fun introduction :D But I don't like two elements:
- i don't understand how many times or how long i can press the button. I think that if you can use a counter or a color to make it more clear it can be funnier to play
- I hope that, in a postjam version, you can insert a restart menu: i restart the game a few times because i can't press any more button but I can't die :S
