On a sunny afternoon, the two little naughty brothers John and Jim, were playing with their rubber balls in the fields near their home. The summer holidays had begun and they were jumping around with no other worries in life than who they were going to tease. But all of a sudden the sky darkened, the birds stopped singing, and a chilly wind sweeped over the landscape! A powerful beam lit up everything around them, and gravity seemed to change direction. In a whirlpool of colours and light, the two brothers kept falling, completely loosing track of time, place and dimension. They were captured in a surreal reality, and nobody was going to help them getting back into this world, except you, hopefully!
You control John or Jim or both (the game can be in one or two player mode) and guide them through five worlds on a quest to defeat the evil king. The worlds consist of linked rooms, and you must find a key in each of them to progress to the next. Each world is full of deadly surprises, including deadly pits and several nasties, related to the level story-line, including robots, blobby things, soldiers, plasma balls, mummies, crocodiles, spiders, birds etc. John and Jim must jump on several platforms, collecting power-ups and shooting with their rubber balls the enemies until the exit key is reached. Some of the nasties need split-second timing to be dispatched, otherwise one touch from the assorted opponents and you go back to the start of the screen losing a life instantly. Fortunately, bad guys don't come back after you've killed them and only the indestructible hazards remain (pits, spikes etc). Power-ups can increase your firepower, having more accurate hits. Occasionally you will stumble over a hidden bonus room or need to find a switch to uncover a hidden platform.
This engaging and intriguing platform game's greatest strength is its great gameplay.
The levels are nicely drawn without offering any special advanced techniques (multi-scrolling, EHB coloring etc) and the sprite animation is smooth. Each level has its own details and uses up to 40 colors on screen (32 for the play area and a few for the top infos - scoring, health etc). Note that for the Amiga AGA chipset version there're more than 70 colors on display, but you wouldn't really notice unless you were looking for them.
The sound is as expected in a typical arcade platformer, featuring cute in-game tunes (related to the level theme) and a few nice SFX in stereo.
