This was a very cute game!
I think that I probably am terrible at is, as I believe that only one of the matches that I made was "correct", but I had fun regardless!
I'm not sure what causes it, but it seems like Godot games that are fullscreen like this one seem to make my mouse cursor vanish, so I had to regularly alt-tab so that another window had "priority" over the game, and then I could see the cursor and select something, and repeat. I'm not saying this is an issue with the game itself, but I do think that this issue is a good reason to include options for Windowed modes, as I didn't experience this with any Godot games that let me switch to Windowed mode.
