My first mobile game

So few days back I published my first game for mobile. Although the game is pretty simple, it was a great learning experience. Looking forward for your reviews.

RGB - The game

Not sure what the goal of the game is. The square doesn’t always collide correctly with the circles. I can only slide up/down/left/right not on an angle correct?

Also, on Windows with Chrome browser I can’t seem to swipe the square at all, it never moves.

Thanks pal for taking time to view my game. Also the game was only designed for mobile devices so I guess that could be a problem.
