Thank you very much for taking the time to play my game. I'm very happy to hear that you enjoyed it.
I have updated the description, as it still said "Z" instead of "Y". I can completely understand the confusion.
I'm glad to hear that you would like to keep following the project. However, I won't be expanding this version much further. Instead, I'm planning a new standalone version, which I will also release here on Itch. I still have many ideas that I would like to implement, but they didn't make it into the jam version due to time, scope, and complexity constraints.
You probably know yourself what jam code can look like and that it's usually not a good idea to keep building on it long-term. :-)
Once again, thank you very much for your detailed feedback.
