Keezees...the Glaswegian web-comic.

Princess Ava wakes up, groaning at both her headache
and the realisation she's been thrown in the local sherrif's
cells again. "That barbarian still owes me a drink" she thinks,
remembering the fight that resulted in her current predicament.
But slowly it dawns on her: this isn't the local cells,
it's an actual dungeon. She's been kidnapped!
Outraged, she breaks free from her shackles and swears to
punish those who would attempt to do her harm...
...for she is the most SAVAGE PRINCESS!

On the menu screen, press 1 to start the game.

The controls are old-fashioned, but we didn't use WASD back then, we used QAOP

Q = Jump/go up ladders
A = Down ladders
O = Go left
P = Go right
SPACE BAR = Fire Swords
A & SPACE BAR = Use Shield

In order to complete the game, you need to collect the 5 power-ups; the
sword, the shield, the jump-boots and the two keys that activate the
horizontal and vertical moving platforms. You only have 5 lives and then
you have to start the game from scratch, so be careful!
