hello! GREAT feedback thanks so much for writing this. All of these are great ideas and I am actually currently working on a revamped version with all of these. When I started making this game I had the idea of the treasure being more expensive further down but when I joined the jam I did not have enough time to complete this. I also bought models of different boats and I had the idea of upgrades that you could buy but again the time crunch really set me back on this. I hope to make these changes in the future with the revamped version. Again, thanks for the feedback!
