Can you 100% this without the DLC and if so will this always be the case and can you keep the 100% or will new things/ach be kept added?

achievement greater than 500 doesnt trigger on this puzzle complete

Question says it all...

I see you are updating the android version of this (last update 2018-09-27, one week ago) When is the next update for steam going to be released? Last update for Steam was 2018-07-19 or 2 months before the last android update... Or have you abandoned this game?...

Just wondering if there are any plans to add any more puzzles in December? I bought all the DLC, so I have already blown through all of the great puzzles that are currently out. :)
