Hi, the game is currently fully playable with a gamepad which is a new feature recently implemented.
The main menu and language selection menu can now be completely controlled with a gamepad and the thumbstick allows to select a level so that you don't need the mouse.
You can save game and control the fish with the thumbstick, continue level and control and select most of the necessary options to progress through the game.
To test the new feature you need to update the game from source or download it from source from the main repository: Codeberg.org (this feature is not implemented on the releases).
