Thank you for playing my game! Well, there is no button for attacking an enemy, but you can essentially carry items, like turrets, which are attacking stuff. So implicitely your carry-button is your attack-button.
i got it, it is more enjoyable now, but it really was already.
That really means a lot to me! I think that this could be made more clear from my side, by adding stuff like a sword or something similar first.
