I actually added some cga 4-color filters to my game engine to play around with that kind of look. Didn't end up going this route, but they still live as options in the editor.
Alley Cat feels exactly like some programmer had a wild late-night coding session on too much coffee (or whatever they had back then) and just let the surreal vibes flow.
That limited 4-color palette (black, cyan/magenta, white) turns the whole thing into an LSD fever dream. Add to that the squeaky PC speaker sound and you got yourself a game!
The gameplay loop itself is unhinged in the best way: You're Freddy the alley cat, jumping bins, dodging dogs, climbing fences, then breaking into people's apartments to knock over vases, eat fish, and court Felicia while Cupid shoots arrows at you. It's like the developer (Bill Williams, ) said why not, went full on "Frogger dating sim slapstick cartoon?" and then just shipped it. And serioulsy, why not?
It's charming as hell and oddly hypnotic. I mean just look at those footprints on the floor, what a cute little detail.
