A simple shoot 'em up game where your objective, as the thief, is to get to the castle to steal the jewel hidden inside. The journey is perilled with fearsome guards - the mighty squares and circles. However, you have a trick up your sleeve. You can switch between a square and a circle which can confuse the guard (if they are the same shape) allowing you to get past unseen. But beware, if the guard sees another guard in combat it will go to its aid.

This my second Ludum Dare submission and it was made using simple HTML+CSS+Javascript without any external libraries (aside from my own boilerplate code written in an earlier game). I also gave myself the extra challenge of not wasting time on external graphics - the main reason I usually fail at Ludum Dare. Thereby, all the game is drawn on the fly and nothing is loaded from any non-source files (well okay - apart from the font).
