The first few minutes of the game I couldn't move my tank. After I understood the mechanism, I started to create some strategies. I really liked it!
But when I went to make a move my game crashed. Here the code to help in the correction:
Error
src / object / Map.lua: 33: attempt to index a nil value
Traceback
