Steam Deck - NeonCode works well - GUIDE

[LINUX-SAUNA]

One copy paste is necessary to the terminal (as is on desktop - the devs hopefully fix this).

1. Switch to desktop mode (long press power button and choose it).

2. When on desktop - click to the main program menu (the Steam Deck logo bottom left) - go to System section and click to Konsole (that's the terminal).

3. Copy this (to link to the necessary folder to make the game launch):
ln -s ~/.local/share/Steam/steamapps/common/NeonCode/{neoncode,NeonCode}_Data

4. Paste it to that Konsole (press the LEFT trigger button of the Deck over the Konsole terminal to bring up the menu - choose paste. Apply with Enter (X-button brings up the on-screen keyboard on the desktop mode).

5. Return to the Gaming mode and click Play. The game launches to launcher. You'll then notice you can't get to the OK button.... Well - bring up the keyboard with the Steam button + X. Press TAB (of the on-screen keyboard 2 times (to get the launcher window's selection to OK). Close the on-screen keyboard and press A to apply OK.
