Sky on fire is without doubt my favourite game in the App Store. I play this game for over 2 years now and I don’t get board of it. It’s physics are really stunning and it’s super realistic due to its damage models. I would love some new updates that include new planes like the Blenheim, Beaufighter, Do-17, FW-190, the g series of the 109, the P51 I, the B-17 or the He-100. I know some of those planes didn’t saw action in the Battle of Britain but maybe you could still add them another DLC like the Me-262, I promise I am going to buy it. Another cool feature you could add is a interior light for night missions and some more details on the ground like little valleys or some more streets so you can better estimate the distance to the ground without looking on the high counter.
PS: I love your game and would be really happy if you might add some of my ideas (sorry for my bad English skills)
