I would advise Humble Mobile Bundle buyers to be careful, not all devs update their apk on HB. An example of this is Anomaly Korea. Google Play lists it as v1.04 while the APK I downloaded lists it as 1.0 on my phone.
Any idea how widespread that is? Maybe I should cut down buying "DRM-free" HB Android games... After all, many of them require server downloads also after installation, which can cause similar problems as proper DRM (ie. when those servers go permanently offline => so much for ever re-installing your downloaded game).
I had earlier thought about that also for HB's DRM-free PC games, ie. do they get updated much? Or do the developers feel "well they have Steam keys as well, so if they want to play the up-to-date version, play the Steam version"?
All the more reason for GOG to get to Android business as well, they generally seem to show more interest in keeping their DRM-free games up to date, even if sometimes some updates may be missing.
