Fine-tuning a challenging, mechanics-filled game is hard! After some feedback (namely that not many people have been able to complete the final boss), I've updated the game to make the boss fight more manageable. I've lowered the boss' health points a bit and also slightly extended the respawn time for the normal enemies that inhabit the arena so that you have more time to try to damage the boss inbetween killing them off. I hope this helps people a bit with being able to complete the game yet also still provides a balanced challenge! My goal from the beginning was to make a small game that was "NES hard" and I still want that to be the case but just to the point that it's a bit more manageable for people who are up to the challenge but were having a hard time with the initial release.
