After analyzing the bugfixes, the features to be added, and the timeframe, this is what I think the problem is:
1. Until I see the code I can figure out a solution. Most likely is a bug with the 3D coordinates not being referenced correctly.
2. This one is in the Artificial intelligence area and as such, tweaking the algorithm can be difficult depending on the implementation.
3. This bug is related to the GUI not being placed correctly or configured to fit all devices, but it's pretty simple to fix.
4. The mailing web service is not configured correctly.
5. There are two options, one is to use the camera to capture the picture that the user wants or have a set of predetermined images to be set as a profile pic for the game or both.
6. This could be a problem with the configuration but it also can be that it is not implemented at all.
7. This feature is very easy to implement, so I'm expecting the bug to be in a configuration area.
8. Same problem as point 1.
9. Again probably a bug fixing task but it can also be a full feature implementation.
With all this said, I'm a video game development engineer and I would gladly help you with your project also if any other tasks rise to our attention we can come to an agreement.
