Although not a game this is really good! Brings back really good memories of the early series in GoT.
You made a really faithful creation here and it looks to follow the original script to the letter.
The timings and suspense are nearly perfect. The whole thing must have taken a lot of time to construct and playtest to make sure all the moving parts are working in order so big respect to get it done in a day.
I think I have seen those horse and rider sprites in another game and the tileset looks like it comes from one of the Suikoden games which always looks great in any early engine RM game so good job with that.
I would advise caution if you do ever consider moving forward to develop it as a full game. Existing IPs are always a bit dodgy ground to tread upon, especially when money starts coming into the picture (even as donations). But making a free to play fangame I think you would be well within your rights.
Good job with this and it's one I will keep my eye on for sure.
