Hi there!
The game was made in Godot 4, which I find very simple to work with. The models used are mentioned in the in-game credits but broadly:
the 'people' are from a creator name Quaternius (https://quaternius.com/packs/animatedwoman.html, https://quaternius.com/packs/animatedmen.html). Which I then strip the facial geometry from and retexture in blender (I also created some extra animations to suit my needs).
the household objects like toasters, soaps, bins etc. all came from https://elbolilloduro.itch.io/ whose models you will find are ubiquitous in Itch horror games. 50% of the games on here wouldn't exist without them lol!
The car exterior came from https://ggbot.itch.io/psx-style-cars, but I modeled and textured the interior myself.
The Takeaway itself and the Player's house I modeled and textured from scratch using a combination of [an old, free version of] Sketchup and Blender, as was the terrain. I edit/create textures in GIMP and edit audio in Audacity.
Good luck on your game!! :)
