The game works fine in desktop mode but won’t open in game mode.

Wine-GE is rather old now (last release is almost a year ago) and thus might not work correctly. Please follow these instructions on using GE-Proton:

Head to the Wine Manager in Heroic, click the "Proton-GE" tab, and install "Proton-GE-Latest"
Head to the settings for your game(s) (icon on game card in library). In the "Wine Version" dropdown, select "Proton - Proton-GE-latest"
Rename your Wineprefix (path is shown in game settings), e.g. from
```
current-name
```
```
current-name
```
to
```
current-name_bak
```
```
current-name_bak
```
. To clarify: Rename the actual folder on your hard drive, do not change the option in the game settings.
Note: This will make game-specific configuration data (e.g. in-game settings or save files) unavailable. If this is an issue, let us know & we'll help you restore them.
