I really liked the style of the game, the use of traditional Japanese doors and the endless generation of the map. I played it a total of three times as shown in the video and for my third try, I have no idea if I was supposed to be able to pick up the key and unlock the brown double door because I couldn't pick it up. If there is a certain key on the keyboard to pick up items, please mention it at the start of the game as on my third try, I think I had nowhere to go already XD. I have played another infinite world generation game before, if I remember correctly, it is called SuperdRug, expect that there was no aim to that game.
I really liked the storyline of the game, it would be cool if there were flashbacks of the main character with his partner while trying to find her and maybe more horrifying events that could occur instead of monsters trying to kill me or random people standing in the hallway. Overall, this is a really cool horror game and it would be awesome to see it continue developing into an actual horror game.
Thank you for reading my comment and I wish you good luck in your future endeavours.
