Boss keeps 2 events at the start and also fires biglaser at regular intervals
User prompt
When boss reach the hp point of 300, it fires straight "biglaser" at regular intervals and keep up other 2 events at the same time
User prompt
biglaser moveslike alienbullet but it fires alienbullets to different location at different angles. It has "biglaser" asset. Add it too classes section
User prompt
Boss should fire 5 bullet at the same time at both of these events instead of 9
User prompt
Boss have 2 events ehen his hp is higher than 300. First event is boss fires 9 bullet at right at the same time and this bullets have different angle. Second event is boss do same thing at the left. The time between these 2 events is 0.5 seconds
User prompt
Boss fires 5 bullets at left and right at different angles in order
User prompt
If power-up level is 5, next power-ups that is taken gives additional score points.
User prompt
Change the angle of "heroBullet" according to bullet's angle
User prompt
Power-up have 5 levels. At fourt level it fires 3 bullet straight and 1 bullet diagonal bullets from left and right. At fifth level, 3 bullets straight and 2 diagonal bullets at left and right.
