I got bored and made this thing. The icon goes to your mouse, so you can move your mouse to control the icon. Avoid the red flashing squares. Yellow means they are currently safe, but will kill you later. The difficulty slowly increases. It starts off with one square, then two, then three. More may be added later.
All me. Made in a day. (26 Nov 2018, no updates yet) REMEMBER, THERE ARE BUGS. Sorry if the reaction time seems unfair, but I had to decide between making reaction time short and making it so long that you stay alive even when you shouldn't.
