Hey there everyone! This is my entry, Mad Maddie!
You can open the "help" page in the game, but I'll also put the contents here, because you have to read it!!! By the way, in every level there is more oil, and more dogs.

---UNZIP THE ZIPPED FOLDER BTW---

The evil dogs from Dogtopia has invaded Earth! Too bad for them, they are really, really stupid. You are Maddie, a golden retriever. Maddie needs to save the world by leading the Dogtopians into the oil! Oil is harmful to dogs. It is considered a weapon of mass destruction, in the language "Dog"! Maddie moves by WASD or the arrow keys. She can stick out her tongue by pressing the spacebar while she is walking. Beware: Maddie has 5 minutes to save the world! Good luck hero, Maddie!
PS:
Level 1 - Up to 10 dogs
Level 2 - Up to 20 dogs
Level 3 - Up to 30 dogs
Level 4 - Up to 40 dogs
Level 5 - Up to 50 dogs
