I couldn't get the game to work with a keyboard, friend.
I discovered through trial and error that the Z key moves the tank forward and the S key moves it backwards, but none of the other keys on my keyboard or mouse seemed to do anything at all...
Sorry, the game can only be played with a controller :/
Oh, I see. The page says "we recommend playing with a controller" so I figured keyboard was possible but just not as good as controller.
Well, I don't have a controller so if you update this with kb+m controls during the jam do let me know so I can rate your game :B
I just added a version for keyboard/mouse! I hope you can test it.
