I also found it weird that at some browser widths the showcase thumbnail images got stretched to 100% width (distorting them, making them more wide). I changed this so that they never stretch. I also left aligned the images too make it look more tidy. All the images still have max-width: 100%, so at narrow browser widths they will uniformly shrink.
Added a showcase item for my game CAT & ONION
