I bought the game on steam but I also want to play on my android how can I do that
Steam sadly doesn't sell Android games, or we would have included it in the package there, so right now the options are either to buy the android version as part of the package here, or buy it separately from other sites like Mikandi or DLSite. The prices depend a lot depending on whether it's on sales and such.
