I just finished the game. Overall, it is a really impressive work, especially for a first release!
Great story and the way it unfolds and makes the player realize the balance between determination to achieve goals and making moral decisions is really awesome. Animations, music, sound are good too! There's a great balance between inventory puzzles and dialogue puzzles and the game is a great experience.
Some things to improve:
The graphics are certainly adequate. However, when you create a game, you have to make a decision as to how game items can be identified to the player. You can either use hotspots that change a label or at least the cursor when you hover over game items, OR if your graphics are designed in a way that game items are apparent visually, then players will just intuitively know that something is a game item. If you look at the questions in the hints section, both are based on game items blending into backgrounds in way that players could not identify them. As much as I loved the puzzles, I spent considerable time clicking around backgrounds to find things and probably would never have found the items that are discussed in the hints without knowing what I'm looking for.
If you really want to take the experience to the next level, try to put in more responses to attempts. Maybe if you give a character an item he doesn't need it should say "Bob doesn't need that can" or something rather than no response from the game when the player tries different ideas.
So, as I said, this is an awesome game in the sense that the story and puzzles are really good. The way it really has meaning to real life really makes the player think rather than just being a funny story that ends with the credits. The fact that this is a first release is even more impressive. So, please take the points I made more as suggestions for your next game rather than criticism!
Congrats
