Use the mouse to move the tennis racket, try to get past 40 points(not actually that hard) to win a game! Works pretty much just like tennis, 1 point give you 15 points, 2 points gives you 30, 3 points gives you 40 points, and 4 points wins a game. Does work, and you CAN get points.
Not ACTUALLY 3d, because 3d is NOT possible with scratch...but...it looks really 3d :D There's such a thing called a ray caster, it's basically pen rendered, like @griffpatch and @WO997's ray casters, it's very hard to do, but this is not a ray caster, but it IS cool! I know, it glitches a bit. Wow, thanks for 100+ love-it's!
