The art is great, and the story idea is interesting. A few more interactions per door would do great, and maybe more than just binary options, though the end
I got stuck fighting the reptile who only seemed to take damage from critical hits or magic and he never did damage to me, so that was a little disappointing. Frankly, I wasn't going to sit around and try to widdle him down for that long. Actually, now that I think about it, all the fights did drag on a bit much. Either bigger damages or less health, or some sort of weakness system.
One thing that would boost the game easily is a small soundtrack. Some synth background music and some hits or even button presses would give it a lot more life.
Overall, great job! Two weeks to get as much as you did is really admirable.
