Your link gives an error 404.
Also where did you upload your sprites and medias ?
It has probably something to see with your host, not giving access to the files, or the files sitting in the wrong place (not in the right folder or something), else all should be fine.
Pay attention, online, "Player" is not the same as "player" (case-sensitive).
Could be, but this is the process I go through:
Zip the folder, named by C2 itself (I never renamed anything)
Upload to my Public folder on my server.
Unzip the contents to its own folder, all names, folders, etc. have been kept, no names have be changed.
I try the app. and it behaves extremely erratic.
