Fun little game!
The UI is pretty and I like the little illustrations for each of the gacha results.
Good job adding the random movement to the "creatures" to keep the game looking alive.
Some improvement points:
- I wish the description card would show the number of dupes gotten or the card's "calculated power level".
- The single roll animation has a small bug that shows the item before the box animation ends. It works fine for x10 rolls.
- However, for x10 rolls I can see the items pop up on the bottom left corner of the screen. To fix this try setting them so they are instantiated further off-screen (99999 in all axes usually is enough)
I reached 1 million coins pretty quickly. XD
