My theory is that is has to do with the goal - in Angry Birds you do bunch of actions and then learn the result, with the aim of completing very specific objective. Sometimes in the middle of the action sequence you already know that it's no good and you have to restart. In Flappy Birds it's simple, just keep doing it, failed, not a big deal, restart, you know you'll fail again.
I was playing it and thinking about zen-like qualities of the game and realized that this game would be completely genius if pipe layout would always be the same. Then zen experience would be complete.
Ah if only I had felt compelled to remake it for iPhones.
Fucking loved that game. Android port is pretty good, but just not the same for some reason. Not as fast perhaps. Flappy Bird made me glad to see someone could do something nice with its formula still.

Maybe the market was just oblivious in the early 90s for not putting cute animals on top of all of these tropes sooner.
How long until we see roguelikes starring cats? RTSs where you draft little fuzzy lions and bears?
I know it's a joke, but on the other hand, it's only funny because a lot of people identify with the sentiment.
