still no luck.....now I can't even make it to the gold key.......... too hard for me.
You are trying the 0.4 version right? It is a bit easier, but not super easy. If you kill the end boss the game starts up again and an increased difficulty level (not that you want to know this , There are over 5 levels of difficulty. Of course the starting level is the easiest.
Killad517 made it to the boss (see above) and so have I, so it can be done. I have never done it on level 2 yet though.
I guess my advice would be, go slow, when entering a room always fire. If your down on armor (they appear random), go from room to room until a armor icon appears so you can armor up your tank. This also works if the playfield is blocking a doorway. The final path to the boss is around 17 screens, after the first two, the random playfield does not appear. Be careful because it's a long pathway. Good luck!
