Thanks for feedback! The game still has little bug so resetting the page is the best fixing I think.
There are more to the game if you read the game description. On collecting more dusts the player speed will increase and bigger size. I know its not right to have important notice outside the game screen, but its the best I can do with the time I had.
The screen below is intended to have touchscreen button for mobile support, but I didn't do it.
