Thank you, I appreciate that you spent time for playing my demo and providing me your feedback.
Well the difficulty level is quite a thing. To be fair, the first design of the boss includes more than 2 phases (with energy shield and missiles). Ultimately I'm delighted to have reduced its difficulty. Regarding a complete game, your feedback demonstrates that options to control the difficulty are a big plus for more players. This gamejam and your valuable feedback highlight to me this important aspect of game creation.
