I just want to say this is one of the ero-games I root for a keep checking back on, even if updates are rare. Somehow, basically nobody else is doing this concept. Well, there's a 3D version with cowgirls that I'm pretty sure is just dead, but I wouldn't substitute one for the other.
So, please keep going darnetal!
Also, the conversation/relationship system penalizing obsessive repeat conversation is frustrating at first - because we've been trained to expect blatant un-realism here it feels "unfair" - but once it clicks it really helps sell the NPCs. If you're ever tempted to back down on it, please find another way!
Vaguely related to that, sometimes I wish there were a middle ground between true Tamagotchi time and just blatant days-on-demand. Maybe steal minecraft's 20-minute days?
