your timer takes the start time and extract it from current time right? i can literally start game click away causing game to pause and start after a minute having 60 score without even moving pls add a timer instead

The patterns feel rather jerky for a pure reaction based game, more specifically the revolving bar of doom. Using a mouse, the difficulty is just at my range. Using a graphics tablet, however, the game became surprisingly simple. Unfortunately I can tell how long this took to make by the occasional hit box errors 30 seconds in. In a future tittle you might want to work on that.

For what it is, it was mildly entertaining and a decent exercise to get used to using a graphics tablet.

Found it too difficult, perhaps it should start easier and get hard more slowly, enjoyed it besides that.

This game doesn't really take any skill. You just need to have a reaction time of about 3ms. People with a slow reaction time should stop being oppressed by game developers like this. It would be nice if you were able to chose a difficulty from about 1ms to 300ms.

Everything is too fast and big for you to react. You blink, you're dead.
And it's not very original, just a reaction event game.
