The reason that MrDots and Braindrop have no delay issues is because their games are low quality garbage, and I'm not saying that to hate, it's just that the games really are low quality garbage, especially Braindrop which I honestly can't get my head around what people like in that literal pile of trash.
That game came out 5 months ago, and it's making over $4k a month and it has some of the most godawful ugly characters that I have EVER seen in any game and with the writing of a preschooler, it seems to be the perfect recipe as that's exactly what people are praising it for...I'm honestly confused as to what the fuck is going on.
But that being said, when you make low quality shit, there's no effort involved, thus you can't miss your deadlines if you only put 5hours of "work" between updates. Again, with a simple comparison of renders between those games and this one you can easily spot where all the time is being put into and the reason for the delays.
That's not to say that anyone likes delays on top of delays, but would you rather wait 3 months in order to get a Gtx2080Ti, or 2 weeks, for a Gtx960..
