Hi,
We published a c3-android game with 10k+ downloads.
I can say for sure that there are around 10% of all downloads who have issues with starting the game.
The main problem:
If they don't have Chrome installed (or very old version of Chrome), they just get a white screen when starting the game. There is no info shown that they need to install / update Chrome... just a white screen.
That caused several 1 star ratings / reviews. On the reviews we could answer that they need to install / update Chrome and everything worked.
But yes, that's a huge problem in C3 and I really hope that this will get fixed soon (if that's even possible)
Best regards.
