Dude the game is a real gem! One of the best of its kind, and I think it's your best game so far.
There are a few problems on the Android version though which I'd like to bring to attention and hope it'll be fixed soon.
The problem is with the saves, when saving a game there are always frequent errors and it fails to save the progress. If the error occurs, the game freezes and I have to restart and lose all my progress. Note that this error does not always happen but it is very frequent and annoying. The game is almost unplayable because of this, and it takes a lot of time to save properly.
I hope you'll be able to deliver a quick fix, and thank you for this amazing game, you're the only Dev whose kinks perfectly match up with mine xD
I am using a Huawei tablet on Android version 7.0 with 2GB RAM and at least 3GB of free space on the internal storage currently.
There are no other issues, it's just the save that's unbearable.
That's the full error message.
