I think it fits the theme pretty well, since I just started hammering down the red button & getting a score of 301 with that tactic.
If it was intended to create a repetitive labour-environment, you did great. But the score-system & audio (which you used really good) are not enough for me to feel rewarded for such a task.. I feel this could be a good starting-point for a game. Like a Level 1. I see 2 ways where this game could be going from there:
It could become a reaction-based game, for which you would need to implement more complex tasks & maybe work on a better reward-system. Also you would need to shorten the time-limit since focusing that long is hard.
Or it could become a clicker, in which case you would need to implement stuff that you can buy for points... which than auto-generates more points, for which you can buy new stuff and so on.
