1. Tap Response
Yup, we've not seen the issue ourselves and can't reproduce it.
2.1 Free Sequence of Ships
Didn't overlook this. For the sequel all ships get turns at even intervals so the player can no longer fire all their guns at the enemy prior to the enemy responding.
Gunnery
6.1 Range:
This is mostly due to the overly exaggerated short distances in game. At short range, minimal gun elevation changes are required to change range, but at long range a large swing in elevation alters range minimally. See the image below and note the non-linear relationship between elevation and range (wow those v1.0 graphics have come a long way):
If a ship moves into gun range it can require a significant swing in elevation to bring the range down. In addition, the inherent error in RADAR readings is also exaggerated at long gun range for this same reason.
6.2 Number of Shells
Number of shells fired/displayed = 1 shell per turret.
Damage done by each shell = Damage * number of barrels of firing turret
We simplified things by merging shells from the same turret into a single projectile. In the sequel, each barrel fires an individual shell.
7. Strategic Map Preview:
The screenshot with the flags is the original v1.0 which was rejected by Apple due to the depiction of a real world nation as the sole enemy of a game. It was replaced with the current map in v2.0. No FoW intended.
General Remarks
The limit is mostly due to the balancing of the campaign as well as much of the code for AI, save data, upgrades etc being based on the 7 unit slots. We could add more ships, but it is a huge amount of work, so we'd rather move on to the sequel which is designed in a more modular manner and will have a much more open campaign.
From v1.0 to 2.0+ we ran into a few limitations, but mostly worked around them. The plan is to extent the concept with a franchise of improved featured games. Based on your suggestion you should not be at all disappointed when we officially announce the sequel
We could add the ability to save single battle data. It just becomes a low priority when we have to maintain an iOS version, Android version, Lite versions of each of these as well as the sequel to work on.
