Good luck on finishing this
I liked this game, I really did. And it was cool how you made a custom cursor. What I didn't really like, was how it got a bit repetitive. You might want to add different objects, some that lose you more points, or some that gives you more points ( other than just 1 extra.). Music and sound is important in a flash, you might want to add that too.
And if you get better at coding, you might want to put levels, and lives. That would make it way better, but I really liked this game, and good luck on finishing it, the suggestions I told you about above might help you. So good luck on the finished version, this is a great start and a great game.
