Story was decent. Definitely prefer the old image style, the new style is 'nice' but not appropriate for the content.
The writing could use some QC, half the time it's Lilly and the other have it's Lily, and wtf kind of name is Math? The other typos weren't too bad, like 'hearth' instead of 'heart', unsure if it's machine translated or just no proofreading.
Speed was ok, good mix of side characters, definitely more enjoyable than NTR Phone. Glad I waited until 0.8 to play though, the content is well paced and didn't feel too rushed.
Note: I was running it on linux under Proton and had no issues with the gameplay, though a couple images, emoji and perhaps a video where just white squares.
