I know this site respects the decision of developer but I think it should be tagged with [Abandoned].
Not in the negative way of "This Dev went playing dead and still milking patreons so we gonna give it a orange tag plate to inform others of this shitty behaviour"
But in a neutral way of "The Dev went on to another project and rushed this game to end and with no future content promised"
Imagine you are newcomer to this game and did not go to last few pages to see the drama, you probably go "hmm this game looks good I will give it a try" and after hours went in, just to get hit in the face with a unfinished ending.
It is understandable for us who followed this game through updates that the ending is rushed, but I think it is unfair for the ones that unaware of it and believe they are about to have nice road trip not knowing the huge hole at the end of the road.
And it could be unfavor for the Dev in a way, as these players who feel cheated by the [Completed] tag will unlikely support the Dev for his/her future project.
