Thank you so much for the feedback! This game was originally meant to be worked on mainly by me and someone else with help from others but something came up and it was left just to me when it came to programming. This is one of the first games I've programmed almost entirely on my own so I didn't get in all the features that I wanted in time and that is why it's lacking polish in many places but I do plan to update it just when I have more free time. The game is meant to be completed by attacking the boss until you go through each phase that comes every ten health that you take from it. I'm glad you enjoyed the look of the game but the gameplay itself is unfinished. Nonetheless, I enjoyed participating in my first game jam and I greatly appreciate the feedback.
