Edit: Doing a make sure test real quick after upload and saw a bug with the timer, fixed it.
Took down the old version to make some corrections; first off, I've balanced it so people who are bad at the game can play easily, while at the same time aiming for a higher score is difficult, let me know how that worked out, also added a timer so that you aren't just clicking for an indefinite amount of time.
Shoot the Kittens trying to get into the portal for 1 point, and shoot the spam for 10 extra seconds.
I do listen to feedback and take it to heart, which is why I redid this to be better. I'll consider all constructive feedback and advice to try to improve my future submissions.
