Why do I have 1 life?
The healthbar is really deceptive here, it says I've got three lives, except as soon as I lose one, I keep respawning in the area I died, making me die repeatedly and loose ALL my lives.
Fix that, put down checkpoints, don't make somebody respawn where they died.
Otherwise, the game isn't bad, you could do some sort of dino death animation instead of making them disappear, but otherwise, the art's pretty ok.
Good work, if you had a time limit, and I have a question.
Exactly what awesome class asked you to make a game about vikings killing dinosaurs and zombie dinosaurs?
