Thanks a lot for playing and commenting on our game. =)
And yes I understand if the cursor feels sluggish but i think it might run better on the windows version, on web version, the game overall runs slower unfortunately. And we have kept the big cursor so as to support the small children visibility and compatibility. We used Pygame for the game and up until now, I have not much of an idea of how to use a OS system based cursor in it with a custom image, that being said, the game is also not very optimised sadly! In the next update I may try to make it more smooth and optimised, wish me luck!
