OKay I got a little addicted to that for a minute :)
You should develop this into a small rpg or roguelite to give you a replay-ability hook. earn new button types and create an array of other emergent buttons and even an inventory where you can collect thing to return hearts or make your life drain and need to collect floor chicken or whatnot.
Anyway, I really enjoyed it, thanks so much for letting me play your game :~)
