Very useful feedback, thank you !
Treads animations might come tomorrow.
The drill was pretty hard to tweak and test, Godot lacks hinge joint in 2D, making it almost imposible to get something sturdy. i would love if the all thing wasn't wiggling around.
The things that have traction are the treads and a bit arround the drill, forward or backward.
I updated the explosion today to be a bit larger to prevent softlock a bit more. I also tried to put the explosion on the back section but it wasn't the best too. I use the explosion mostly to adjust myself and to get room for a u-turn
