Thanks for the Android version!
a couple points of feedback:
- the images being white at the start is surprising, misleading. With 120 Common it is likely that you won't notice the content of the images during you starting 60 draws.
- draws don't recharge when the game is in the background, unless you fully close the game first.
- with 30 photos per tier, no animation and draw refill faster than DD, I end up spamming draws without really looking at the images.
- in the Gallery, the count of each card is tiny on mobile. The white text is invisible on photos drawn once and on some of the photos with a pale corner. I suggest putting a heart or a rarity-colored circle behind the number.
- once you have all Commons the game speeds up even more. If Rare girls have 1/3 chance to give 15 draws every 5 draws, you only need normal Refill for the first hundred draws of each girl before it's nearly self-sufficient. Higher tiers have it even worse, I had over 2000 draws when I finished.
- If the plan is to add more girls in future update, you are headed towards the same problem DD faces: the Common bonus becomes harder to reach with each girl added.
