[André Simões]

First my congratulations to the game. I am fan from the old SH3 and I am glad to see finally a sub sim to smartphones. After maybe 20 hours of playing your game this is my review and suggestions.

Note that english is not my native language. Sorry in advance if is difficult to understand some parts.

1 - There is no external view, but I see this as advantage. Let me explain better.
I can imagine that could be implemented a career in the game starting in 1940 as commander of a type 2 u-boat. As we advance in career new u-boats would became available. The type 7 , next 9 which we could use to get to east coast of America and finally in the late of the game the spectacular XXI. Since there is no external view is far more simple to introduce this.

2- The same way it would be great to see upgrade trough the game. New torpedoes, like the eletric ones ( perfect to kill the escorts) and the option to make them follow a pattern. A Snorkel is a must buy latter in the game.

3- With the career advancing, new ports could be available to dock and latter in the game only in Germany, Norway and Denmark.

4- Would be great also that the crew members could get experience with patrols. The gun crew members could have difficulties in hitting a ship far away in the beginning, reload times would improve with veteran crews, etc...

Gameplay

1- Fix the problem with escorts. If a ship is hit from starboard as example they only can tell that from what side the torpedo came not my exact location. Also the way they move was to improve. There as times I had 7 ships above me without caring about hitting each other.

2- I made a test with the sonar in escorts. In a night patrol I was following a escort from behind maybe 500 meters away and I hit flank speed. The escort immediately came to hunt me. Well that's not possible because the sound of the propellers of the destroyer could not make possible to listen what is behind him.

3- In the interface below I saw there is space for more two options that could be implemented. One of them is to control the definition of which torpedo individualy. Draft, impact or magnetic diffuse. That would be great. And this bring up to next section for hard core gamers.

4- I don't want to know what is distance, bearing and speed of the ship. I want to find out. Look at the periscope and make my manual calculations. Open the chart, try to know what ship is, speed, bearing, and with this I could set my torpedos to better hit the target. This could be done with a new map where we had tools and could use marks and a simple chronometer to elaborate a plan of attack.

Visual and sound

1- Depth of view must to be increase to 10 km ( maybe a option in settings for smartphone with good hardware )

2- Das boot music? Would be great. Or a Gramophone with classic music from that time.

3- German speechs to the commands I give. =)

4- Better waves. Big waves for storms with rain and thunders that would be nice with u boat bouncing in the surface. Also patrolling in the north sea I would be nice to see icebergs. With big waves the deck gun can't be used. Also I remind now. When I am running from a escort in the surface right behind me I can shoot at them. Not real because of the u boat tower.

5- Would be nice to see flares in the sky at night when the convoy is being attacked from the escorts in searching.

Also I was forgetting. With would be nice in career as I mentioned to see ships without escorts in the beginning ( 1940 ) . Maybe later in the game we could call support to make a wolfpack attack. Bigger convoys with 30 ships if this is possible. To lay down in the English channel. I think that is not to deep there and in others parts of the coastline. So we could sit and with a full stop make the u-boat practical invisible to the sonars.

Sorry if I spoke to much. I see a lot of potential in your work and I am glad to see what as improve already.

Keep up the good work.
