I feel like the confusion does entirely come down to the presentation of the game up to this point tbh. It's one of those things where I'm just gonna have to let future builds put all the pieces together for the player, since I'm sure on the surface the lightbulbs don't seem like much, but every ounce of the game was built around figuring out how to create a game of chance with electrical power at it's core. The blackjack part came as a direct consequence of the lights!
We'll see how things go in time haha. Some things obviously won't end up working out in the end, but I deeply appreciate you giving it a shot and providing feedback!
And heck yeah... This is a Godot appreciation zone. All my homies love Godot B)
