One Horse Power(Godot C# 24hour GameJam)

There is an Alien invasion but your car has no engine, and that damn horse won't let you ride it. Using your devine intellect, you attach the horse to the car using a rope, this is ONE HORSE POWER, longer you survive the better the score.

Press A and D for left and right, mouse left click for shoot, try to survive as long as you can. What score did you get?

All art/code is my own, however for the art I used a reference image and copy pasted the colour pallette.
