Looks like an interesting weather-survival game ... Unfortunately, the download for WinOS platform consists only of a single tiny EXE file (624.5 KB, compiled: 10 Dec 2018).
Clicking the EXE file leads to the launch error: "The program can't start because UnityPlayer.dll is missing from your computer."
If the game was created using Unity v2017.x onwards, it has a unityplayer.dll dependency. (Not so for games created with older Unity versions.)
As such, the standalone exported ZIP package for a playable WinOS build should have a directory structure similar to the following:-
- \Through the Storm_Data\ → subfolder containing game assets
- \Through the Storm.exe → executable "wrapper" that calls the below DLL
- \UnityPlayer.dll → engine code, allows game to be played as standalone on WinOS
Thanks !
