it is very difficult to find an opponent

I suggest you promote the game more,spent a couple of hours tabbing in and out and
have the test 1$ still alive and well and unused too
the chat is broken, it displays "false" at the top (whatever that means) refreshing the page doesn't help either
This is the main problem of the low populated PvP games, the matchmaking is not working, because there is simply no one to play against.
I can't remember if I have seen a successful gambling service with only pvp games which remained popular, most of them seem to come and go very fast.
If I may suggest something - adding some 'vs. house games' should help to kill time and mitigate problem, also adding faucet to the site wouldn't be bad idea.
True. I was able to play like 3 or 4 games but after that, cant seem to find other players.
