Thanks for your excellent feedback, I shall definitely take on board all of what you said and use it to try to improve my game. When I made my boss fight, I actually thought it was too easy but I'm used to retro hard games like the earlier Mega Man titles. It's going to be hard for me to judge the correct level of difficulty but it is a major issue that many people have had so it definitely needs fixing. Thanks for enlightening me on what makes it difficult. This is going to help me a lot.
