Heya! We used Ren'Py as an engine! It's a python based visual novel engine that is very easy to pick up and with tons of helpful resources out there! We're glad you liked it!
Loved the vibe and aesthetic, neat installment into walking simulator kingdom. The visual department (modeling/lighting/set design) is genuinely a reason to check it out. Keep mind of the photosensitive warning though, even without epilepsy it can be a bit much on the eyes at times.
