Cool concept and gameplay  is chaotic and  great. I think the increase in the intensity is paced well and the sound effect of the timer adds to that. The player having a damaged state is good and the way the arrows collide is oddly satisfying.   Like others have suggested, add a replay button to improve  because it would be easier to replay and hiding the cursor as well.

Despite it not really being a one-button game, I really liked this game! A very cool concept using the mouse and the intensity ramps up at a really good pace. I would suggest having a retry button at the end instead of forcing the game to close after 10 seconds so that players can keep trying instead of having to reload the game. Overall though, a really good job :)

Next level of one button game, a no button game! Great game though really, I like the mechanic of dodging arrows (might be biased). I like the sound effect of the arrow firing but I think it would be better if the arrows don't collide and if the game auto restarted. 10 arrows / 10 off screen squares.
