Hi,
Truth be told we prefer when people report bugs via bug report form on discord, but there's no obligation to join, so yeah, this passes.
Regarding bugs you've found - thanks for reporting them, let me address then separately:
1. This sounds like a Godot engine having a beef with Android devices, from my experience with other mobile Godot games, if you give too many inputs in a short time, the engine gets confused and stops reacting to any other input - if you did just that then ... Yeah.
Currently the only solution is to be slower with taps (no idea why this problem exists, but I haven't noticed such behaviour in any other mobile games made with different engines like unity, ren'py, etc..
If that's not the case then please ping me, I'll add it to our bug board.
2. This is unfortunately pretty common issue, also Godot having quarrels with Android, simply go to app settings and clear cache (not storage!) this should help with both crashes that exit the game and situations when game does not open from the start.
I suspect that the problem lies in how Android in general handles Godot software, not in your phone as others have reported those crashes before and clearing cache helped them.
Hope this helps,
Cheers
