Billy and the ball

This is a submission for Trijam #262. Theme: Wall bounce.

Billy the robot is playing around in the laboratory. Try to prevent the ball from touching the ground for as long as possible. The game has no end, just try to get the highest score you can.

Controls :
Move with ←/→ or A/D and jump with ↑ or W.

True story. Spent 3 hours to make the game, then almost 30 minutes to add particles (robot thrust on jump and ball explosion on fail), then 20 more minutes to try to debug them not working on the web version, and finally another 5 minutes to remove them and revert the game to the state it was in one hour before. 👍 So I guess the game you see on this page was made in 3 hours somehow?
