Sad news to hear after being through everything over all this years, but gotta give it to 'em, it's been one hell of a ride. Through all the highs and the lows, they manages to keep players at their feet and battle it out in the game. I can't regret anything about the time and money I've spent on the game and I'm glad I've supported it with both through all these years.
Now, since there are really no courses of action for the game, I'd like to suggest one in hopes that the Devs could find some use of it if read.
I belive that the best way to try and continue EpicDuels lifespan is porting it to Steam (aswell, as transfering it to Unity). Thus it creates a possibility of having a larger playbase and a larger playerbase provides a bigger possibility of income. People are always interested in indie games, so on paper it seems like a good idea. It also creates a better marketing, as in: there are youtubers who play an indie game for a few douzen minutes and upload it to YouTube. They share the game to their viewerbase and thus it creates a possibility of increased player attraction.
All in all, Steam as an option seems as a best course of action. Sure it may backfire, but there's that hint of a possibility that it can be a smash success.
That's my opinion, take it as you want it.
In the end. I'm glad I was able to be a part of this and would gladly do it all over again. Thank you for all the hard work and faith you've put in the game and I can only wish you good luck for the future.
