wtf?
Is there standard an 'unlimited life' system in this game or something? Cause i think i died a trillion times the 10 minutes i played your game.
I like the concept of the coloured square powerups that become more powerful while collecting. I have never played 'raiden' before so i cant really compare this between the original.
What also was extremely annoying were the overpowered levelbosses. Not only did they shoot 1000 pixels per second in every direction, also if u have a good poweruped ship and encounter a boss, he will probably destroy you in a couple of seconds. Then u respawn again, but only with the standard level 1 gay weapon. At that point it basically is a matter of flying directly into the boss while keeping the shift button pressed...
Try to balance the game a little bit more. But i saw in your profile that you are only 13 years old. And although this game needs working it still is a very good job for a kid ur age. Im sure that when u are a little bit older and keep on doing flash u will make some real masterpieces in the future. Take care!
