Thanks for the feedback, Diadantist! I noticed the choppiness in the browser too (do I need to use more preloading in my code?). I also don't know why there's no lighting or world environment effects either. (also nice pun haha)
Ah yeah I wish I had that extra week I missed! Would have loved to add more animations and polish like the tower falling or boats sinking. There's also another unused enemy boat type sitting in the files. The wizard also glitches out if you don't move the mouse lol. And I thanks for the reminder about the paused sign, I keep forgetting about that.
Thanks for the encouragement! I might expand on it later into a fully fleshed out and polished game if it has the potential.
