Thanks for the comments!
I see what you mean about post-jam updates :) I just did the most critical ones, which took like 2 hours.
But I agree with your comments! I thought about the things you've mentioned and I totally agree that I should go more for bonuses than for penalties :) And it would be cool to add some clicker mechanics separate from rhythm, like you've said - with point for clicking in good time.
And for the bells - yep, I should have placed semi-transparent positions for the full bell state I guess :)
