I can confirm that the controls seem much more precise now
Playing this version is actually the very first time that I play X-Com seriously, getting further than only the first terror mission
It plays just about flawlessly on my phone and I haven't encountered a single bug on it.
I've also tried it on my Galaxy Tab 3 7.0, on which plays very comfortably due to the increased screen size. Though, only on the Tab I get the "stuck key" bug when for example purchasing stuff. I consecutively tap on for example the upper arrow to increase the amount of scientists I want to buy, and at some point the button gets stuck and the number increases ludicrously fast. Tapping the button again frees it, so it's not a major problem, but rather annoying. Also only on the Tab, it's sometimes nearly impossible to center the view on an enemy in sight. The little red "1" is shown in the corner of the screen, but when I tap it, it only sets a path for my unit to move. It even shows the description of the button, but it doesn't work. I haven't figured out where or how to tap it to make it work, it just sometimes does.
Finally, I really don't like the "swipe unit to turn view" function. When I mean to use it, I rarely make it work, whereas I often trigger it accidently while dragging the view around, wasting precious time units. I find that "long press tile to turn" works very well already, so if possible it should at least be an option
