8444, that was my high score.
Movement in this took a bit to get used to, but once I did it was actually a lot of fun! It just makes more sense that a game which takes place under water would feel more slippery.
And I can definitely relate to having to scrap things that were going to be core elements of your game (there was a boss fight that was 90% complete for my game which I had to scrap last minute), but the adaptation you made works really well.
Also, really nice job on the 2.5D visuals. It's not a common style, but you nailed it.
