Yes, it’s actual text doc. I’ve found changes in Czech version, will add it in next update (waiting for “Bug fixes and improvements” section here: Defold roadmap H1-2019 - Q1 summary). Thanks!
About other improvements, I have no plans for doing gameplay/mechanics/UI updates in LyL 1, have plans for technical updates only. I supported LyL more than one year, it was fun, but I guess, a life cycle of this game is over. All my mind is focused on new prototypes. Btw, thank you for the your research!
