A day ago or so, I saw a comment under some video about Alex that I've since forgotten the title of that really stuck out to me. It's definitely something I can agree with too.
Generally, the user said that Love Letter's announcement drove away some of Alex's more skeptical fans and attracted them to it instead, resulting in him losing quite a lot of fans. This in turn forced Alex to actually give a damn about working on the game for once in his life and begin to finally put the finishing touches on Osana and release her after years of empty promises. I can imagine that Osana's release likely brought back some of the fans that turned to Love Letter because to them, Osana finally being released to the public means that the game is obviously being worked on and will be finished at some point or another.
The user noted that Alex only worked his ass off to release Osana because he saw Love Letter and its primary dev Logan as a threat to his game, something I've also seen a few kiwis both in this thread and in the YanSim clone thread say. Think about it for a second. Until mid-ish July, just how much of Osana was completed was nebulous; no one but Alex knew when she was going to be implemented in the game. However, once Love Letter burst on to the scene and Alex realized that he had a major competitor, he emphasized Osana even more than usual in his video and blog updates. If I can remember correctly, the user basically said that Love Letter lit a fire under his ass and made him realize that, if he didn't work on his game quickly enough in order to release a major update (Osana in this case), he's going to lose a substantial amount of fans going into the future.
However, now that Love Letter is no longer a thing, both the user I'm talking about and all of the kiwis here (including me) have noted that Alex has significantly relaxed on updating YanSim and essentially working on it at all. Wonder why? It's because Alex no longer has a competitor threatening to usurp the spotlight. No one significant is lighting a metaphorical fire under his ass anymore. I won't be surprised if we don't see any signs of Amai's progress until yet another YanSim clone bursts on to the scenes and threatens Alex's hold over his fans. Only time will tell just when a brand new clone shows itself and forces Alex to actually work on his damn game.
