At this stage in early development, it is not possible to accurately tell if this game will be good or bad. From what I have seen so far the potential is there to be good, but the potential is also there to be bad. I hope this game becomes good because I enjoy good games.
Here is my breakdown:
The renders are mostly nice. Although some renders should be replaced. For instance, some renders have a black background, other times lighting changes between two shots a moment apart in the same room/scene. (noticed this happen once at the school) I also noticed some inconsistent clothing changing outfits mid-scene without any sort of explanation. Spend a few minutes fixing those images up or reshooting them, and it will look much more professional. Both animations were fluid and nice. Overall good job with minor room for improvement.
Engrish? No, it did not appear to be Engrish at all to me. Characters spoke well, didn't really spot any spelling or punctuation problems. There may be a couple, but I didn't notice any. Good job there. Keep up the good work.
Bugs/coding? So far, I didn't spot any bugs or coding errors. Good job there. Keep up the good work. (Not counting 2 different outfits in 1 scene)
Freedom Element: By freedom element since this is an NTR visual novel I would consider this a measure of are you forced into the cheating by the game mechanics or does it allow you the choice. Well... You have one choice to tease a man or not. You have a second choice to fake it in bed with your husband or actually give some constructive criticism trying to make him a better lover. This would lead me to believe that there will be a possibility to be faithful and pick who you cheat with if you do cheat. That's good. However, in the somewhat broken classroom scene You do change outfits mid scene. So as a creator I think what they want to do to fix that is to go back to earlier before she leaves for school, and give her the option of which outfit to wear this day. Jeans or a short dress.
Originality? Unfortunately for this creator, this has started out as a story that has been told in countless games already. Female protagonist, young broke married couple. And she is probably going to cheat. So far that is 0 originality. If they want this game to be a great success they must bring some more creativity to the table, and make it stand out from the crowd.
If development continues I will check this game out later to see if things have improved. Good luck to the creator, and good job on your tech demo. You are going to get haters. And you are going to get people telling you to add this or add that. Keep true to your vision, and make your art.
