There is no need to compare Dev from this game to Dev from Milfy City. There is a complete difference between them.
Inceton adds updates every few months and is working on two games (as far as I know)
And ICSTOR? you can expect there won't be even one update a year. Now, instead of working on the main game, he makes a pointless second game. He doesn't know how to regularly update the game Milfy City, he wants to make a second game. No sense.
I bet we won't see any updates from ICSTOR this year, and Inceton will surely come up with something.
I will add that I like the changes that have now happened in Echoes of Lust. The game is more interesting. Dev knows what he's doing. Love Elizabeth, awesome milf.
