Great news
It is worth so much work which you do. Idea with the torpedo is cool but it will be still only shooting to the sitting ducks becouse enemy doesn't hunt for player. Just compare this to Aces of the Deep
And finally stupid question-what with a donate? It is possible? Sorry for my bad english
Ps-what do you think about adding real time in game and few elements of AOTD campaign(data of hunted ships,cooperation with other submarines etc)?
