He hasn't even finished writing, for at least another 4 months.
Yep people saying February like the renders just do themselves after the writing is done have no idea how much work and time it takes to properly design, pose and probably polish some details and then rendering each image/scene and give an enough quality final product, besides all the code that has to be written and other little extras each game have like music/sound etc and then the test phases. At least this game don't have animations so it cuts some of time to finish but like you and Kenthaa said in the 2nd quarter of the year at best but people shouldn't be angry/surprised if it was in the third quarter also.
Edit : Depends a lot on how many people work in the project, how experienced they are and how much time available they have to do all the work. Not all devs can be so quick like the dev of the game in my avatar that usually makes in 4-5 months a very high quality product with animations even though they are smart enough to not write and work on too extended episodes for each update (and much less branching than in Eruption Imminent), I got tired to tell Classy Lemon how much well organized they must be and experienced in the visuals programs that usually is the most time consuming part of the job, but at the same time CL spoil us
, one day they need a larger break so they won't burn out and all they will hear is complaints because we were spoiled
.
Edit2 : Think I read somewhere more than once in this thread that the dev of this game is a she, but not really sure, that is why I often prefer to say they/them to refer to the devs, it is not because I have any information that isn't a solo dev or that it is a team, it is just to not assume any specific gender.
