Hello!
Thanks for the feedback, I'm glad you find it interesting! The seasons will show the town changing as the player has an influence over it. The game opens during winter with the town mostly closed up, and abandoned due to the kidnappings. New seasons bring hope and light to the town, with the player also restoring it.
The seasons will also affect the woods where the main battles take place, with each season having different sets of monsters and enemies you'll face. Winter themed monsters during snowstorms etc.
As for the retro style, it's really about bringing that nostalgic look to the game, while also having modern features that players are used to. Auto saving, character creation, etc. In the same way that a game like Stardew Valley does it so well.
I hope you'll give the game a play when it's released!
