; This is the CHEATMODE, type it in correctly and you will be
; given 9 lives!
;
; Today the world is full of evil,
; Today the world is mean,
; But in the future near,
; Insects will be so evil,
; No man has ever seen,
; Or dared to fear.

; Anyway, for anybody who is interested in a perfect example of
; how-not-to-code a cool game, here's the complete source of
; EVIL INSECTS. I have exclusively for you documented almost
; every single line of this source, so you probably won't have
; any problems understanding this code. (Hmmm)

; This source is about 1700 lines long, but that's mainly because
; of the level-definition data statements in the set_baddies part.
; The game displays everything with 50 frames a second.
; To achieve this, I had to cut down the number of enemies and
; also their size. Some of the shapes in the shapes-files are
; unused, mainly because they are ugly and I am lazy.

; Well, that's all I'm gonna say about this source, except for
; some legal stuff. You may not recompile this source and
; distribute it under the name EVIL INSECTS. I don't really care
; if you modify it somewhat and give it another name and spread
; it all over the world, as long as you don't say I screwed it.
; You may also use some parts of this source in your own programs
; if you like, coz I don't really care for copyrights about this
; code.

; Oh yeah, thanx to Mark Sibly and Simon Armstrong and all
; those dudes at ACID for creating the best Amiga programming
; language, BLITZ 2! (If it wasn't for them I'd still be
; struggling with AMOS!)
