Please add credit to Edvard Grieg for the music.
I really enjoyed this, I love the concept and I ended up having a good time trying to press the keys in time with the music, however a few things to be aware of. Firstly any time I pressed Alt the game would pause and I had to click back into it which was very annoying but also disrupted the flow of everything. Secondly remember that different keyboards are configured differently so where my apostrophe is (') was a completely different location to yours so that made it difficult to follow. All in all it needs improvements but I enjoyed it
