Countdown

A mad professor has planted a bomb in a sewer. You are trapped in his house
and you have to escape it by collecting keys to open bars and get to the top
of the screen, get through a jungle collecting keys to open the sewer and
finally get down to the sewer, also collecting keys – but this time to defuse
the bomb. The bomb will explode in a certain period of time, which the player
can set at the beginning. 2 minutes, 2 minutes and 30 seconds, or 3 minutes.

In each level there are bonuses for the player to collect. Collecting these
will award the player with extra points. Also each level has different
hazards. The house level has turrets and lasers, the jungle has man-eating
plants that are dangerous if they open their mouths, but harmless if their
mouths are shut and there also falling coconuts and the sewer has vine-esque
plants that will enlarge and shrink.

After the bomb is defused the game will start in the first level, the house
level, again. Should the player not defuse the bomb in time the game will be
over and the player can write his / her name for the high-score list.
