Bug (or feature? :p): I ran into the enemy camp... I clicked some questitem... I died... I respawned right where I should be for completing the quest and I still had the item :). Easy win...
My first game (and only:s) was also something like this (shame nobody thought the same as this guys ^^). You should have a look at your game, right click, disable pop-up on the flag and you won :). Same problem as I had, try using an object which moves towards the mouse with a certain speed and check on that :).
My keyboard reaction is too strong for this maze... Also it's a long way and no savepoints or something. I died before the end I guess... but I really don't see an end-point. Besides... you have tagged the game as music and I don't even hear some background-music. I think that tag is wrong ;-).
Nice concept... Maybe you should consider both good things and bad things? Use other pixels or something to get money and use money to upgrade (f.e. emergency shield, faster movement, counter-attack, ...). Just some idea's, maybe you can use them ;-).
Try boosting up the graphics... Maybe you can at least make a random algorithm, which allows you to go as far as possible, but it's to easy and boring now... sorry :)
