I'm not one to tell people how to spend their money... but in this case I'm going to recommend that if you want to support a better Dev that you give your money to new Devs instead of these, since these developers are well supported and even with the very good support they receive per month, they will not improve the progress of their game.
In other words, your money will be better in the hands of another Dev who needs it more and is worth it, because if you support this Dev hoping that the speed of updates and the game will improve, let me tell you that it will not, just by reading the people's comments from the last few months you can see the reasons.
