STORY/GAMEPLAY:Well, there is not much of a story behind this game to be honest. The action is a stereotypical action shooting platform mayhem and basically all you have to do is run, jump, squash, shoot and generally splash your fins around, defeating baddies and killing massive bosses at the end of every level, all these in a joyful and very colorful wrap! You are given three lives, but if you collect all the gun-power up items found and then die, the level is impossible to complete because there no other items available to increase the firepower you need to beat the boss! More on that, the time limit to complete a level is ridiculously low I think. Controlling your character is ridiculously frustrating too, and is mostly close to impossible, resulting to easily fall into deadly pits or onto incoming nasties. Collision detection is another huge problem here, but if you master the chunky controls, you'll might be able to progress further, after 10-20 times of trying.
In general, Mysterious Worlds is an absolute joy in terms of sounds and graphics, but the in terms of gameplay just awful. Controlling properly (where necessary) your character is mostly close to impossible.
GRAPHICS/SOUND:The game's visuals are fine, offering smooth scrolling, parallax scrolling, and nicely detailed backdrops, and it is obvious that a great deal of care and attention has been taken over them. Two planes of parallax scrolling are used, and each level is littered with brightly colored details (up to 32 colors on screen). Sprites look rather small, but nicely designed and animated too.
Each level sports well matched to the game's atmosphere tunes, while the sound effects are solid sampled gun-shots and explosion noises fulfilling their purpose, but doing little to enhance the game.
