On the other hand they don't seem to care about what was released. The game has some crashing bugs (not on specific action - it just dies sometimes) but I haven't seen any update on android yet. They don't seem to care that the game is still marked incompatible with nexus 7. (even though it works on nexus 5 just fine) It looks like they just want to release it for every platform possible, but don't care what happens next. Support forum is mostly just users. I hope I'm mistaken...
Both the combat and the strategic phases of XCOM are very boardgamey in their own way. And it works, it's great fun. But in terms of game design, it's about as far away from X-COM as you can get while still retaining the same basic components.
FWIW works perfectly on my 2nd-gen Nexus 7.
