Well, being here from the start of the game and watching the progress, I think now with the new update it would be a nice idea to have a special ability for each weapon. These special attacks should use all the energy or maybe be used only once per round. The hammer should have a ground smash attack and knock over any robots and kill the weaker mark 1 or 2 robots. The bow should have a spread shot of 3 arrows and the sword a triple spin attack.(3 spins). If le dev sees this, it's just an idea for the upgrade bot.
