Pushover

The game consists of 100 levels of increasing complexity over nine different themed worlds. Each level features several interconnected platforms holding a number of "dominoes". The aim is to rearrange the dominoes, such that with a single push, all of the dominoes are toppled, thus opening the exit to the next level. There are 11 different types of domino, identified by red and yellow patterns, each with different actions. The player controls G.I. Ant, who can move certain dominoes by carrying them one at a time. Various factors can result in failure to complete a level. As well as toppling all of the dominoes, the player must be able to access the exit door once the dominoes have fallen. For instance, the player will be unable to reach the exit if a ledge leading to the exit has been destroyed, or if a gap leading to the exit has not been bridged, or if a line of dominoes lie across the exit. G.I. Ant may die by falling from a large height, by falling off the bottom of the screen, or by being crushed under a falling domino. The player is then greeted with the message "You Failed, You Died" and has to restart the level. Also, the level will be failed if any dominoes are destroyed by landing one domino on top of another. Each level has a time limit during which it must be completed. However, if the time runs out the player is still able to continue with the puzzle if they wish. By pausing the game once the time has run out, a small hint will be displayed, giving advice on how to complete the level. As a side note, the hint for level 98 informs the player that the game's designer cannot remember how to complete the level without trickery ("Use a drop! There is a way to make it work with a push, but I can't find it!"). The themed worlds, in order, are an industrial complex, an Aztec world, a space station, an electronic world, a Greek temple, a Medieval castle, a Meccano-inspired world, a dungeon and a Japanese temple. Each world has 11 levels, making a total of 99 regular levels. A packet of Colin's Quavers is retrieved after each world, with nine packets in all to be collected. Many of the early levels are tutorials demonstrating how each type of domino will act. Often there is only a single solution to each level, though some levels have multiple solutions. The final level, level 100, must be completed using dominoes with hidden markings. A password system allows the player to continue an earlier game, without having to restart from the first level. Additionally, upon completing a level the player gains a token, which once a level has been failed, allows the player to return to the point before the domino push, rather than having to return to the initial state of the level.
