This is a Choicescript game written in less than 4 hours for Ectocomp 2019.
I had a lot of fun with this one despite its size. The author managed to cram a lot in. There's a 'build your monster' segment followed by a series of moral choices. It provided a feeling of agency beyond its substance and had solid writing.
Loved it! If you want more monster stories from this author, they also wrote Each-Uisge from IFComp 2019.
