Thanks for taking the time to play (and hopefully rate!). This is something that I thought about as I was developing the later levels, but I didn't implement it because I didn't have time and also because the current codebase means it wouldn't be a simple change (I've learnt a lot about how to set up a robust workflow in Godot from this project). Also I don't hate that it makes it a little harder; there's a penalty for hitting the Submit button when wrong, and on later (non-existent) more difficult levels, I think not having the lights tell you exactly if you've got it wrong or right might be a good thing, rather than a bad thing.
