Greetings, Lealo!
Firstly, thank you for the kind words!
Secondly, regarding the map - our mapper, Muizer, is currently making a brand new map for our mod, which can be expected to be implemented in the following months
Writing up guides on units and other things is something we have been considering for a while now, and we will work on drafting and publishing them along with our next version, v4.0, which we will release this summer.
Units stats are also in the process of rebalancing for the next version
