This game is 90 percent complete, but not quite there. Once finished, I plan to release Android tablet, Linux and OSX versions. Tasks still to do:
  • Compose original music tracks.
  • Draw graphics for between-level sequences.
  • Review difficulty curve over all levels.
  • Re-rewrite hiscore code to remove Internet dependancy.
  • Add option for player 1 to play as Mrs. Dwarf.

    Mr. Dwarf
    Mr. Dwarf is currently highly disgruntled due to repeated burglaries of his hard-earned dinner. After one theft too many, he is now out for revenge! When encased in his shining suit of golden armour, Mr. Dwarf is bestowed with incredible powers of endurance, and is able to withstand any earthly threat. Once once, though.

    Mrs. Dwarf
    Mrs. Dwarf, being the loyal partner that she is, has become equally aggrieved by the constant re-appropriation of culinary treats and has joined Mr. Dwarf on his quest to end the rat menace forever. Her more feminine armour no less effective, just slightly more visually appealing with its convenient openings for lipstick and hair!

    The weakest of the monsters, the rat will simply walk back and forth waiting to be caught. Beware an angry rat though, as it will try to fall or jump in order to catch you!
    Bees, while still relatively weak, gain an advantage over rats in that they are able to fly. They move in a simple diagonal pattern, changing direction when they get near a wall or spikes. Bees will speed up when angry.

    Redback spiders will lurk quietly on the ceiling, crawling back and forth. If they notice a player nearby however they will swiftly pounce down onto their prey!
    The snake moves in a similar fashion to the rat with one important exception - upon seeing a player they will spit a glob of deadly venom at them!

    The tick is small but intelligent. Even in its regular placid state it will move in the same manner as an angry rat. Because of their small size, they are also difficult to target with a slam!
    Snails are slow moving but tough. When attacked normally they will not die, but simply lose their shell and become a slug. The safest way to take them out is to slam another monster into them, thus killing them instantly.

    Slugs are faster moving than snails and capable of launching themselves through the air at their prey!
    These fish at at home in the water and unhampered by slowness while swimming.

    Evil venus fly trap plants will lie in wait and devour any player foolish enough to wander into their clutches.
    Annoying pests at the best of times, flies pose additional danger to dwarves. They fly around more erratically than bees and after landing can scurry quickly back and forth.

    Green frogs will continually bounce around, making them more difficult to catch. They are also excellent swimmers.
    Worker Ant
    Worker ants are relatively easy to avoid, but when fed will quickly grow into more dangerous soldier ants.

    Soldier Ant
    Soldiers move faster and are more intelligent than their worker siblings. In addition, with just a little food they will become queens.
    Queen Ant
    After an ant has eaten enough, they become a Queen. Queens are just as fast as soldiers and can also breath fire. Furthermore, they are only one meal away from spawning additional ants!

    Whitetail spiders are more intelligent than other monsters - they are aware of nearby players and will use the landscape to track them down!
    The bat moves in a straight line until it hits a wall. Although simplistic in their movement, bats have the ability to fire a burst of sonar to take out an unwary player!

    Cloud of Doom
    This unkillable cloud will appear if you spend too much time on one level. Beware, as the only way to defeat the cloud of doom is to complete the level before it grows too large to handle!
    King Rat
    This mighty creature is the ruler of the rats, and impervious to the player's net. It can only be harmed by slamming another monster into it! King Rat will roam the level searching for a player, and upon spotting them will charge at high speed.

    King Snail
    The absolute ruler of the snail kingdom is far too large and heavy to catch in a net. In addition, its shell provides protection against all attacks, leaving only its head vulnerable. While King Snail is too proud to chase down enemies itself, it can use its snail army to destroy its foes.
    King Fly
    King Fly is quite literally the lord of the flies. Far from the timid garden-variety fly, King Fly will roam around with its entourage of underlings in tow, running down anything in its path!

    King Ant
    All ants bow down to King Ant, the ultimate ant overlord. King Ant is an enormous fire ant, endlessly covered in flames and able to create ant sustenance from its body. Its flames are so intense that they can instantly melt through solid ice!
    King Cat
    The elusive King Cat masterminded the great food heist, and is rumoured to weild powerful arcane magic...
