How was Melody's ending rushed? The news about DMD development is that they're switching to a five week development period rather than 4 to give themselves more time.
It was rushed like hell! The last 2-3 updates (mostly the last one) were clearly made under the pressure of having to finish it till December 2019 and that was clearly visible in most compartments: story, writing, dialogues, spelling, animations (or the lack of them), etc. Even by some renders although that's MrDots strongest skill.
EDIT: And most of all, one could feel wile playing that the minds and the hearts of the makers were no longer by Melody in the last 2-3 updates. They didn't FEEL for it anymore! In their minds and hearts the game was already finished and they were now focused on the next project. And that was highly unpleasant for anybody who invested their feelings in this otherwise very good game. We didn't deserve that rush, mostly not at the end(s)!
As for DMD, since that's the "real good one" out of all MrDots games, i will just wait 1 week longer if it must be, because I know that, unlike by Sunshine Love, it will be worth waiting.
