I've just discovered Osmos in Android market and would love to buy it. But when I try to run the demo version on my NS I9020 with Android 4.0.3 the game runs fine for ~3 minutes (duration changes, I suspect the level complexity is a factor), then it starts to be slightly choppy and after a couple seconds it crashes to home screen. With no crashed dialog, nothing. Immediately after the crash I see elements of my homescreen coming up one by one as if being restarted. Seems to me the game continuously eats up RAM and when there is none left it crashes.
Hope this helps. I love the game, I've played it on Windows and would be wonderful to be able to play it on my phone. But as it is, I am unable to complete even basic levels in a demo.
