You encountered all of the issues i know of haha, sorry for that. The spacebar to interact decision could have definitely been changed, ive noticed people have been mentioning that as an issue a lot. The sail landing was hard to make work right, and the current implementation certainly is buggy. If you want to reset your save, I'm pretty sure its in "%APPDATA%\Godot\app_userdata\Sail" and you can just delete the "save_data" file. But yeah- thank you for leaving a detailed review! it really means a lot and will be super helpful if we ever decide to finish this up
About your closing note - it certainly is very personal, I have enjoyed sailing a lot throughout my life. To translate the serene feeling from that experience into a similarly meditative game is so rewarding, i hope to make more games in the future that capture that feeling.
