Cute take on the genre.
Here are some things I noticed:
It became very unclear over time what the best picture would be. There are so many factors I can't all keep track of, and so many things I don't know the interaction of. This isn't necessarily a problem, but I think a little score breakdown of why a particular picture, or just the best picture, got the score it did, would go a long way.
Dandelion field and fall area both say "Your photos get x1.5 currency" so it is unclear what the point of dandelion field is.
I don't know what "x10 900 per photo" means.
After dandelion field, follower gain becomes a bottleneck, with several runs required with no upgrades to reach the next goal. After that next goal I could buy out almost every upgrade unlocked past it with other currencies, only to have to grind for followers again.
I feel like I was vaguely punished for buying loot boxes before maxing the slots in them, since the cost goes up exponentially and I can't go back and get the extra items from the old boxes.
Opening many loot boxes was tedious and meant I ended up never reading any of the actual outcomes.
There doesn't seem to be anywhere to read what you have in terms of cats or items. You also can only read what they do when you get one.
