Thank you for review!
We had actually intended to add more mechanics like having progressive difficulty as days went on, more interactivity with the review screen, etc. Unfortunately I had to chop those things due to time constraints (I had family holiday stuff going on).
Thank you for letting me know where to find that fix . A friend of mine wasn't able to play because of that issue and I honestly didn't have time to look up how to fix it, so I greatly appreciate that info! You also guessed correctly about the invisible buttons. I was having issues connecting the signal to the manager node as each boat was created and destroyed, and felt I didn't have the time to find a more appropriate solution (another victim of the family holiday time cut). I've since found how to get that to work and looking back a little more research would have save me some pain but hindsight and all that.
