first, his name is diamond head, not head blast, you're probably think of heat blast.
Second, using the mouse for controls makes no sense when the arrow and wasd keys are right there.
Third, the graphics were mediocre at best, repeating the same animation over and over.
Fourth, allow us to choose when to make use of the super jump. More then once I fell to my death because I was forced to super jump.
Fifth, I know it may seem cliched, but an upgrade system would greatly improve this.
Sixth, the individual aliens on the show were unique and interesting, combining two just seems like either you were to lazy to come up with your own new alien or you just wanted a really over powered alien.
