This was really well done! You took the Ban Ban games and really made it into something that was a more cohesive and fun experience! While I do think each version of the game has its own vibe, yours really nailed the spooky side and made it pretty freaky with the changes to the darkness and the monsters! Well done on everything on doing it for the first time and learning a lot, hope to see more of your visions of the games!
(Also a small bug I found was that in the vent, you can lock yourself in the middle of the walls and have to restart to get out. Not sure if it helps!)
