Left click to shoot fire balls, right click when at or over 50 points to shoot energy spears. Kill 3 bosses, 2 mini and one main.
There is a lot going on at the same time, which may make players confused. But I see you have already improved that.
If you play the middle version, you essentially have infinite health. That would allow you to see all the bosses and animations you might not get to normally. I am also considering getting rid of the smaller enemies as they are just distractions for the player.
