Hi Nyancos! (/≧▽≦)/
Do you want Steam Achievements in Nyanco? (ฅ'ω'ฅ)
Here is the way to activate that function in this game.
1. On the Steam client, search for "Nyanco" and right-click. Then select Properties.
2. Opt for the Nyanco_Steam_Achievements_Ver on the BETA tab! ε-(•́ω•̀๑)
3. If it has been successfully applied, [achievements] will be displayed next to Nyanco.
Nyanco BETA build is a little unstable.
But you can do it, Nyanco Player! ヽ(=^･ω･^=)丿
