Hey there! Good to know you are enjoying the game. ^_^
1. A small chest should have appeared on the desk after you hit the statue, you can get a charm from it.
2. Did you delete them completely, or are they still in the trash bin? You can restore any file still in the trash bin (right clicking any files there should show the option, and you can even restore all files in the bin if you right click the bin itself). If you deleted them completely, you might try to check the properties of the folder the games were in, and see if any previous versions are available (but you must be careful if you changed anything else, as this might restore unwanted changes as well, assuming there is even an option available). One final solution might be trying to use a program like recuva, but the sooner you do that, the better, since your computer starts overwriting the data once it thinks you don't need it anymore.
