square puzzle game

I made this ( imcomplete) game that currently only has 1 level ( infinite mode)

how to play ?

click on a square to select it then use the arrow keys to jump over an other square ( the space in the direction needs to be ocuupied and the space one further then that needs to be emty )

if u get a high enuf score ( powers of 1.5 ) an extra square will spawn ( these will have a star on them )

score calculation :
the selected square's score + the square where u jump over * the line multiplier ( is high the higher u are )

the game does not reset properly if u press reset so if annywanne has an idea of how to remove it I would like to know
