I understand. If you are not satisfied with the pace of the game, change it in the settings(gear in the upper right corner). The parameters of the "player speed" and " speed up ". Thank you for your feedback (^.^)/
Control is performed by clicking the mouse(just tap on the game area). And you're right, the game uses physics from Unity3d. I hope I got this right. (I do not understand English well, I apologize in advance). Thank you for your feedback (^.^)/
