1. Good Idea, Original.
2. I don't like the "catching backdrop" AKA as the 3rd Screenshot.
3. You spelled "welcome" wrong when you talk to Misty.
4. I don't like the text for talking.
5. Don't forget periods.
6. The mapping is too simple for my tastes.
With some improvement this could turn out swell, just needs some tuning. Great idea though.
