fantastic good game designed but level 5 and beyond is way little to hard to be honest you have zero inch or millimeters marigins for a slight misstake and the red walls are so tight with enemies you need ice cold touch or insane skills to complete them.i completed to level 8 but htat reached my end with classic C64 VICO joystick (Vico Command Control (Powergrip) i used as reaching the most original spiritual feeling of this amazing good game, i think litlte level adjustments could do it more fun to play as for now its way to hard for me to continue. wish there was a level editor with it to make own levels to chare as additional feature to this legendary good game !!
I've just played a game of this PC version and reached level 20. Obviously, while making the C64 version, which took a few months, I gained a lot of practice and, above all, mastery of flying, which is what is needed to succeed in this game. Personally, I've always used the keyboard; at this point, I suggest you try it yourself with the keyboard to see if you get better results. Otherwise, if you have trouble getting past level 8, you'll have even more trouble in the later levels. The game has been tested by my collaborators too, and the difficulty has been thoroughly evaluated. I can't change the levels because only one person is having difficulty. If several people complain about the game being too difficult, then we might consider making changes. I'm referring to the C64 version, however, since I'll most likely never touch the PC games again, given the lack of interest they've shown in recent years.
