love the game but it is missing a few things, this is just some constructive criticism and a few suggestions
What the game is missing is a long-term goal, sure surviving is a short-term goal but there is really nothing to work to after the mechanics are figured out and the game play is mastered, there are the transformations to find, but they are difficult to discover naturally, and I had to look in the comments to see how it works. Maybe add a cryptic hint about eating too much of the same type of food. There is also discovering every food item, but that feels like more of an extra thing that someone would do after they have completed the game and not a goal for someone to complete
There need to be endings. Starving and getting arrested are game overs but they aren't phrased as endings, I think it would be better if they were endings 1 and 2 out of however many endings there are, and an ending for each transformation too. Going back to my first point, a good ending (and a long-term goal) could be saving up enough money for something that drastically improves the main characters situation, I don't know what this would be yet and it might require expanding on the lore but I think the game would improve with it.
I don't know how I would fix this game play wise, but the whole game is slow to progress, I have spent a few hours playing and I have only gotten two transformations fully. Maybe add some different game-play for the money gaining part.
This last thing is more of something that I would find funny, but I noticed that after purchasing some items (I don't know if it works on all of them) a number flashes on the screen of the vending machine, and inputting that number of yen allows you to get the same item again, I think that putting in 69 yen and 420 yen should get special food items, but this is more of a humorous suggestion than a serious one.
That's everything I have to say
Edit: it just occurred to me that another good feature would be if the gallery shows more info about the food, like how much you need to pay for it or a short description.
