Marble Run Cannon Battle in Godot (idea: MIKAN)

A Marble Run simulation that is loved by my son, but in Godot. Thanks MIKAN's youtube channel for the idea. Currently, the game has only two modes: CannonBattle and CannonBattleV2. I hope to add more in the future and fix the bugs I have now. You can also watch a YouTube video of it playing by itself.
