Alpha 0.04 :: Optimizations Round 1

Mercury Fallen Alpha 0.04

A huge thank you for all the support and great feedback. I’ve managed to fix up various issues as well as further improve performance. This is the first batch of fixes to help improve performance and overall stability in the game. While this is mostly a bug fix release there are a couple of new features and improvements. Alpha 0.04 now available over on Itch.IO.



Crops now have the ability to be cleared after a crop is selected. Just click the new clear crop button and the current growing crop is removed so that a new one can be chosen. No more need to deconstruct crop fields to change the crop.

The capacity meter for inventories has been improved and will now show the current and max quantity of the inventory. The progress meter is also more visible and will become yellow when the inventory is over 60% full and red when the inventory is completely full.
