Pretty good!
I have to give you props. For this being your first ever flash this is pretty damn good!
You said so yourself the graphics arent very good, well pretty much everyone can improve on there graphics in one way or another. Yours are decent. I like them, they arent all fancy or whatnot, but yet, they arent crappy.
As many people have said this, but it really was to short. But yet, you only had two weeks to work on it. But defintally make sequal to this. I will be looking forward to it if you decide to make a sequal.
The puzzles werent hard. Maybe make them a bit harder next time?
Anyways, I liked the game all in all. Just wished it was a bit longer.
Oh I almost forgot, the intro of the game, maybe add a skip button? So that way if people want to play it again they can skip it?
And then in the end, it just goes to a blank white screen. I think you should either add a "To be continued" on it. =] Just some suggestions.
