Crazy awesome game
A little heartbreaking to reach the end of the content for the current update VN aren't always captivating like this so the wait for the next update is definitely going to be suspenseful!
Regarding the half release issues, maybe it'd be possible to set up some kind of php login server to embed in the alpha releases? I'd hate to see such a promising developer lack the revenue to keep up such a wonderful passion project.
Anyways, absolutely loved the game and would 100% recommend, my only suggestion is actually for the players... If your device can, then go to your dev settings in your phone settings and force gpu rendering as well as 4xMSAA it might help to really improve the animations for VN's on mobile devices
