I played the game and this is very well put together. TLDR: The art is amazing, the writing is very enjoyable though it personally went a bit over my head, the puzzles were traditional.
Keeping in mind this was for a game jam, double thumbs up.
- The aspect that strikes as especially noteworthy is the art and the character design. The pieces you included set the tone extremely efficiently. "Show, don't tell", they say, and I personally disagree; because I personally would agree more with "don't use words where you could use images", that is to say that showing and telling should have each their place and time. I think you did very good balancing between the two, even if occasionally you run into engine limitations (the monsters in the dark section are constricted in the 1-2-1-3 RPGmaker animation and it doesn't look especially good; the lamps inside the castle are seemingly affixed into black nothingness and the light they emit is handled in different ways than the light shown in the very first map). That being said, as you see, my complaints are nit-picky and very minor. Your drawings especially are gorgeous, and the way you rendered the foliage and the cliff at the end of the hearing puzzle are beautiful.
- The way you handled the writing is also pretty novel and can lead to various interpretations, as such I'm not sure I really understand all that happened (are we talking about gods or just angels? what is the seventh moon and how/why does it represent the end of the world, and how/why is it personified this way?). That being said I did find some typos here and there, but nothing major. It did strike me as peculiar the usage of the blue characters to indicate "purpose" and "the seventh moon"). I could hazard a House of Leaves reference, but I don't know how to make it fit in this context.
- The puzzles got the job done. Without infamy nor glory, but you were smart to turn these otherwise not memorable moments into ways to enrich the lore a bit. Still not sure how the shovel helps with them, though; and I was not able to complete the tombstone puzzle normally after I got the shovel.
- I hope you'll forgive me, but I took a peek under the hood and noticed the abundance and complexity of JS plugins. It is evident you know your way around them.
Good game. It does tell an interesting story in a very enjoyable way.
