Hello Anthony,
This is not scam since we do not run away with your money and you already get our product so it cannot be scam, i would rather say it’s a delay with update and if there is a delay it must be with a reason.
The Particle feature is already implemented in Agama Pro v1.3.8 (pending release), but there was change since particle should be a quick and small update but i have increased a TO DO list with some other serious changes and code improvement.
It’s better for us to delay with update until we are 90% sure that there is no any serious bug missed out which could affect above 1000+ cleints.
We have all right’s to delay with update as long as we need if the purpose of delay is to protect our clients from unwanted bugs.
You can always ask for pre-release update and we will provide it to you without any bug free guarantee, but it’s in your interest to get bug free update than quick update with many downsides.
Again, if you want pre-release update with particle feature please let us know and we will provide you proper download link.
Best Regards
