Addition Kingdom

Meet Luke, our mini-math hero!
He’s got a huge problem, well, actually, a ton of problems. The evil Lord Quotient, ruler of Algebra, is bent on having all the number symbols, so he has set his sights on Luke’s home town of Addit! The only way to fend off Lord Quotient’s minions is to add, and add, and add. The more you get, the better your chances of beating him off.

How to play:
A yellow number will appear at the top of the screen. Your job is to collect numbers that will add to that goal number in the time allowed. Orbs will crawl across the screen, and each orb has a different value written on them.
Use the up and down arrow keys to move Luke. Collect the number orbs as they move towards him, but be sure to dodge the oncoming enemies. Hit two or more and they will deplete your score!
Your collected total will appear in the upper left corner in white. If you go over the goal, your defenses will crumble and the enemies will invade Addit. Be sure to add to the right amount!!
Each successful match will give you a bonus, restarting your lives for the next round. Things will get harder as you move into the final waves!
Good Luck!
