Probably try advertising your client like I did. It would be best to since yours is being hosted externally and wont be shown in itch's search results. I'd make a module like latch to just show a message in front of someone like a unskippable ad. Yes, it does annoy people but it does the job perfectly and if you know how to play your words, it can work wonders in getting the client used, even better then just annoying them.
