Congrats on your first Godot game and first game overall! It's a very good one for a first project, the gameplay works well, the visuals are cool and you even have nice sound effects and music. You can pat yourself on the back and be proud :)
Also kudos for putting playing instructions on the main screen, some more advanced devs around here haven't done it and it makes the gameplay harder to discover. It took me a while to understand how to get fish without getting burned, but the dash became my best friend. I got up to 15 points (max points challenge beaten!) and then accepted my fate as an octopus.
