ok, here's some cleaned up comments I wrote as I played the game:
There's some great music. Written yourself? what tool did you use?
I like the graphics too. Looks like you spent a bit of time on them.. I like the random desert scenes.. You could make them less random and more predictable by basing the scene used on the ego's position.
The night scene looks very spiff too.
The problem I had was finding the way to where the oasis is. How are you supposed to find your way without walking lots and dying in the process? You shouldn't have to die to solve a puzzle. Perhaps some intermittent messages that you might get every few screens. "you think you hear something south" "you think you hear someone drinking to the west" "the sound gets fainter" "you cannot hear the noise any longer, perhaps you are going the wrong way"
I didn't figure out till later that I was scaring the camel away. At least you can swap the screens and he'll be back again. It wasn't until I entered from another side of the screen that I realised. Hint? After 10 times the camel runs away, you could go "perhaps you're doing something wrong".
Does the coin only appear once every 255 times? isn't that a bit too rare?
I like the tilde key..just press to look. not your usual feature.. perhaps advertise in the intro? titled: "differences from ordinary agi games". I don't think many people look up help
"take" is not understood.. only "get"
should be a message to "alt-z to quit" at end of demo.. or maybe just quit for the player
nice site.. how long has it been up? will you update? did you know that time quest has since been updated?
will you need a score of 2000 in the end?

do you have the rest of the game mapped out?
