Most of your problems with Chaos;Head are all fixed in Noah. Chaos;Head is an incomplete version due to its parrallel devolopment with Steins;Gate, which lead to a lack in budget at the time. While I still think Chaos;Head gives me one of the most unique experience, it may not be your cup of tea.
Anyways the complete version Chaos;Head Noah (which has 9 endings) and Chaos;Child is much more better. While Noah has't had English tls yet, Chaos;Child is available now on Steam. I'd recommend you give it a try.
