It's a bit boring if it's really what they plan to do. Also, when they reach 400pts of relationship, either it's the end of the game (great, more time allocated to make more DmD, if they don't start another game) or they could just make a new chapter of Melody and push the relationship points to 600. I didn't check, but money-wise I suppose Melody earns more than DmD, just because Patreon has more reach than Subscribestar, so I don't really see them abandon Melody after the next 2-3 updates, unless there's a new game coming to replace it on Patreon.
