Not only do you have a really nice art style, but you've also finished a lot of very detailed backgrounds, events and character illustrations! Incredible work! The setting is also a fairly unusual one and there's lots of neat little details to bring players fully into your world!
The narrative is interesting, and you add a lot of visual storytelling to keep it engaging. All of the characters felt truly distinct and have lots of cute reactions. Wylo's facial expressions are great. The pixelated transitions feel slightly off to me simply because your art style is so painterly, it doesn't feel like something that should dissolve into cubes. I like the attention to detail with custom menus and fonts.
The routes are a bit convergent for now, but there's some differences further in the story to remind players of what they've done. The web version gives me errors on decision screens, but I can still make a choice.
The music is great. I don't know if Fluffy wrote the main theme specifically for this game, but it fits the environment perfectly! You could try adding sound effects to match some of the visual gags and transitions for added immersion.
Very impressively done! There is an incredible amount of art in this game for a single month of work, and you've put it all to great use in your overall narrative!
