Sea Dragon

Year 1983, a PC is an expensive machine with a CGA card and a speaker capable of beeping in four tones. Under such conditions, Sea Dragon from Adventure International was born — a game that drew inspiration from arcade machines and brought it to home computers with results that are, to say the least, debatable.

You're in a submarine, navigating a horizontally scrolling underwater cave and trying to get through a series of obstacles alive. Enemies are shooting at you, there's a threat of crashing into walls, and the whole thing moves at a pace that leaves barely any time for thinking. No story, no context. Submarine, cave, survival.

Gameplay relies on reflexes and memorization. The cave doesn't change much, so after a few attempts you know what's coming — but the game will punish you anyway if you react even a fraction of a second too late. The difficulty is set hard and without mercy, which was the norm in 1983, but today it can turn many away before they properly get into the game. The controls respond well, you can't fault that. The problem lies elsewhere.

CGA graphics do what they can, but four colors in the combination that the PC happened to offer aren't a visual treat nor the standard of the time. Arcade machines looked better, the Commodore 64 looked better. The sound from the PC speaker adds a layer you can tolerate for about five minutes, then it starts working on your nerves in a way the designers probably didn't intend. The game simply carried all the technical limitations of the platform and then some. That doesn't mean it's bad — it's just an experience with sharp edges from every angle.

Sea Dragon today suits mainly those who love pure arcade challenge without frills. No cutscenes, no saving, no item collecting. Just you, the cave, and trying to go further than last time. You can click through it in a browser in a few minutes, and if you don't mind the game repeatedly killing you before you have time to get your bearings, it can be a pleasant quarter hour of nostalgia over how brutally simple and yet brutally difficult games back then could be.
