-there were a lot of objects in the castle that you could walk through
-also multiple spots where you could walk through the railings from the 2nd floor to the 1st floor or from the main stairs to the 1st floor
-the bottom part of the letter 'g' was cut off in the message boxes
-when the blue haired lady talked to me for the first time "...there's been an accident", that letter S went partly outside the message box borders
-in the beginning there were 2 sparkly tiles on the main character room's floor, but interacting with them did nothing (they just vanished?)
-after talking to the maid, the maid sprite just took steps left and right and then vanished
-when controlling the black faceless sprite, the main character's sprite flashed briefly at the beginning of that scene + also the tip of the stepping sprite's black foot was visible also on the black character's idle sprite
-when waking up after the bloody hand scene, there is a scene where Shun is talking a lot, but Shun's sprite isn't in the room with you?
-the inventory screen was somewhat glitched (at least when using a keyboard)
*if you pressed arrow keys fast, the menu movement froze randomly for some time
*pressing the 'd'-key when on item screen, brought up the menu screen on top of the inventory screen and they started flashing
*you have to press the 'esc'-key to return from the menus, but that was also the game hint key and displayed the hint message repeatedly
*there was a 1 or 2 times when the menu glitched so that it didn't register pressing the 'esc'-key to get out of it and so I couldn't continue
-when loading the game it took you to the menu screen instead of the gameplay screen (maybe intentional?)
-also on the loading screen the character sprite graphic cut off at the head level
And finally: after all the drama in the castle I moved out of the castle through the town. Met some elf-boy, went to the beach, but couldn't use the boat? Then I couldn't figure out where to go, went back to the castle and was suddenly assassinated to a game over screen without warning. That wasn't cool

I hadn't save in some time, so didn't feel like continuing.
