The writing in this was a little shaky- not the second language feel, I can't give anyone flack for that. So But on the next scale up, there were non-sequitur type moments where I wasn't sure why some lines followed up others, or moments where I clicked a dialogue option only to realize it was doing something other than what I expected it to do. The conversations didn't quite feel natural. However, on the next scale up, the overall scene progression did feel natural. The progression of scenes didn't feel rushed or slow. Most of the dialogue choices were pretty obvious as far as which one was 'correct', but all it did was make me less stressed about getting a 'good' ending haha.
The themes of depression were very surface-level? But not to the point where it felt like a negative portrayal, it's moreso the same omission of detail throughout (also mentioned in eevee's comment).
I didn't realize the backgrounds were AI generated right away, but I really liked them. (This is what people should mean when they mean AI "makes art accessible"- it adds uniqueness where otherwise there might have only been stock photos, or no picture at all.) It made me feel like it might turn out to be a horror game of some kind lol
