I realized there is the Save in menu, means the player can save their progress ANYWHERE.

Although this won't be in the change log, I've removed the Save from menu, thus player must save their progress only via Pillar of Pilgrim.
And for those have downloaded Wandering Brawler before this blog posted, enjoy your mobile Pillar of Pilgrim :D

Meanwhile, the progress of Scene #2 and the rest are rolling in slow pace. I must adapt the college' new schedule.
