Electricity
Main: You are inside the inside of an electronic thats breaking, you are avoiding sparks and wires.
Secondary: Flowy gameplay that gets faster and more intense at the level goes on (Required) Movement that show the level it breaking down more over time (Required) Keeping to a yellow and gray style (Could be adjusted)
Optimization: I in every case would typically take quality, if its not fun, then its a flop in my opinion. If it's hard to see it, than it becomes worse for the player. Id rather make 1 good level than 4 mediocre or bad ones.
