Thanks for the feedback guys, this is really helpful! It is strange that the first level is so much harder than the others! It must be a sweet spot where the AI strategy works particularly well. I'll put a lot more thought into the next set of levels so there is a more gradual difficulty curve :)
The controls are a bit more complicated than I would have liked.. I play with a joystick and it is awkward to have to take one hand away to hit space.. although I do like having the three modes so maybe I could alter it so holding fire and using a direction selects each mode. I have one page of memory set aside for level data at the moment which is enough for about 70 levels. I'm not sure how many I'll have the patience to design though! ;) Rob.
