Snowman Sledge Battle!!

I made this for a game jam with the theme "Snowmen go Sledding".
There are two snowmen, each controlled by a player.
Both players start with 10 snowballs. You lose 2 if you get hit. You lose if you run out of snowballs.

Controls:
Green Hat Snowman:

• Accelerate: W;
• Turn Left/Right: A/D;
• Throw Snowball: Space.

Red Hat Snowman:

• Accelerate: Up Arrow;
• Turn Left/Right: Left/Right Arrow;
• Throw Snowball: Period/Full Stop.
