Destropolis is – hands down – an incredibly fun game to play, and the overall gameplay loop, including weapon selection, power-ups, perks and the music selection, is balanced just right to enjoyable again and again.

However, as a casual achievement hunter, I can't help but feel like the (later) achievement unlock conditions are unreasonably (and exponentially, to add) grindy.
I've played Destropolis for about 30 hours all-in-all, and managed to score a total of 50,000,000 points during that time. Extrapolating said number, it would take close to 600 hours – 25 entire days – to reach 1,000,000,000 points and 100% the game – which, even with as much fun as the game is, is a lot to ask of a player.

I'd like to know if those unlock conditions were selectively chosen with the massive grind it would entail in mind, or if they were chosen arbitrary with the excessive amount of time it would take to reach them not taken into account – because if it is the latter, I'd kindly ask if there could be something done to make the later achievements more accessible or replace them with a different set of achievements that would not entail another 500+ hours of simple replay – because looking at the global leaderboards, I hardly doubt a lot of players unlocked (or will ever unlock) those achievements the legit way.
