If you didn´t get the game from here ... you probably got a leaked test version ...
Expect bugs and glitches ... and do not expect your saves being compatible with later releases ...
I don´t know anything about mobile gaming ... games on such small displays are a no-go for me ... except for puzzles like Sudoku or Wordle ...
I am on a dev-build - 0.3.3.21 - and I can tell there are some new features coming ... even if you can port savegames between versions ... expect them to be incompatible ...
