Thank you for the feedback and checking out the game! I decided against the pickaxe moving the cart, because there would then be no way to attack an enemy if the cart is in between you and that enemy, since throwing the pick would instead move the cart instead of going over it. I might play around with it though to see how it feels!
All good! I always appreciate suggestions! I have actually been playing with the vehicle movement way of moving the cart, and also having the stomp for when it gets to heavy, and that already feels great!
I'll brainstorm ways though to make it more clear that the pickaxe is being thrown over the cart in terms of layering. Maybe they can grow when thrown and then size back down after traveling a bit.
