Hey! I loved the idea and I'd like to give a few advices. I firstly think that it would have been great to have some kind of an ability that matches with the limitation like a grappling hook that increase the temperature! I wasn't able to finish the game, maybe I was too bad or is it set to be endless ? Nevertheless, it was pretty fun and well presented but I would have loved a lot of juicing in such a game, if you want this video explains well juicing with godot: https://youtu.be/_qxl7CalhDM
Lastly, it would've also been cool to have some 3D aspect, like a collision for the boat and a Y sorting implemented.Have a great day, and it would mean a lot it if you could check out "Water The Kids!" the game I made with coldrebirth!
