Hello everyone, as you can tell from my response comments there's now a new and greatly improved version of NecroHarvest. With difficulty being the main concern we made lots of tweaks to the general gameplay to be far more generous while still keeping the game difficult enough to still punish you for slacking off. However there's now a proper learning curve and far more visual/audio polish to make the game both more fun and even better in the visual/audio department!
For an example, even for me back then I averaged around 70 seconds and couldn't ever break it past 120 seconds as the mob scaling gets too high to do anything past that point. Now its possible to get 400-500s+ with practice semi-regularly. However, most people starting off will not get anywhere near there (some friends who tried the update still often started out getting sub-1 minute) but as you play the game more you will see some genuine improvements with the game being more generous!
