BUTTERFLY, from Pulsonic, is a simple game programmed entirely in Basic and consequently is rather slow when compared to other modern arcade games. You are a spider, chasing and eating a minimum of 12 butterflies per minute to survive.
The hazards of life on the windowsill are represented by the purple spider eater which lurks behind the curtains and who looks like an over-fed Pac-man. A joystick would help in raising the game from the level of mediocrity but unfortunately it is not designed to be joystick-compatible. Being in Basic, that could be remedied easily. Also the spider is a little slow to react and though it is possible to catch your prey, a good deal of practice would be necessary to enable you to catch the required 12.
Unfortunately, little attention has been paid to producing an interesting screen layout. The spider is fairly convincing but the butterflies are somewhat lacking in sparkle and the background is dull. Although the program costs only £1.99, it is what one would expect to find as a magazine listing, not as a commercial program.
