Not that hard actually. At least, I think so.
Laggy/battery draining is not even a big problem, just depends how many lines of code it would contain. It's not an a game like "Pixel Gun 3D" that didn't made for a "poor people" who cannot afford a better mobile phones. The recent update now doesn't allow even to play from emulators anymore which sucks. Everything depends on how apps code is optimised to make users experience more enjoyable.

It would be hard to code and probably very laggy/battery draining but it should be possible for a newgrounds mobile app
