I like that they have many languages available, it's very helpful to know what people are saying about your game! It is also easy for me as i can just send them my files without having any problems with their services or anything else. Sometimes when you get an error while uploading something there isn't much help from support so make sure everything works before sending stuff off otherwise things could be lost/missed out if not checked first time around (especially important during beta testing). The only thing was sometimes some text would come up but then disappear after being uploaded which made no sense at all since we had already sent our file through several times previously and nothing came back wrong yet this happened more than once throughout development process - luckily though these errors were minor enough where its still possible to fix manually afterwards rather than losing hours upon hours work due to bugs coming later down line causing issues further into production phase etc.
