In the maedracan desert I found a rifle, but when I attempt to pick up bullets in the area nearby, the character drops the gun, but picks up one bullet, but it doesn't register in her inventory. Then after that the game is bugged altogether, I cannot pick up more than that one bullet, and I cannot pick my rifle back up. However, when resetting the game Pirizuka starts off on her flying rock with the rifle in hand. Also, on low quality mode the text in the land and planet description box is extremely blurry and nearly illegible.
The ammo is meant for vehicles. The handheld weapons don't run out of ammo last time I checked. Deleting app data doesn't fix everything Skeleton :P
