Game that I have purchased on the store does not work

I have purchased a game off of the Minecraft store called "cookie slap" by Team Visionary. As I load up the game and try to start a match. It would say that the game can not start so to lobby being laggy. I then thought it must've been my WiFi or my lan cable that I use. So then I restarted my router and reconnected to the WiFi without my lan cable. And the same message keeps coming up. I then went to the YouTube channel of the created and on the YouTube video of him showcasing the game, in the comment section there are also other players that are experiencing the same issue that I am. I'm wondering if the issue is caused due to the new update or if the developer was scamming a fake game. I couldn't get any info on how to reach out to the game creator and thus the reason I'm writing to you and see if we could get any help or information about this situation. Thank you for spending some time on reading this and I'm looking forward for a reply back
