So this is a weird thing. I noticed it once on my Android phone (S7) after downloading a new update where I had added bunch of sounds and music to my game. On the first time load of the newest version, the game froze at the Construct loading screen. A restart of the phone fixed the issue and I didn't have it happen again for any new updates.
Then today I opened up access to my game for testing. One of the first comments I got was that the game doesn't get past the loading screen (OnePlus 5), and that the bar freezes about 2/3s of the way across, pretty much exactly where mine froze that first time. So I suggested a device restart and, sure enough, the problem went away.
Now obviously this is not an ideal situation. If the game requires users to restart the first time then you can imagine how bad this looks. I'm not sure if this might be related to loading of sounds (currently the game preloads sounds at startup) but that's my gut feeling based on the fact that this didn't happen until I added a bunch of new sounds/music. The game itself is small in size at 10Mb so I don't see what's causing it to hang (corrupted sound file maybe, if that's possible?)
A link to the game is below. While I won't post the c3p, if a member wants to have a look inside I'm happy to communicate via pm.
