The game is fun for a while - but you quickly hit a hard wall. Meaning practically zero progression unless you leave your phone running it and keep spamming x50 dungeons. What the game needs is a beastiary encyclopedia (to show where the animals are for the collection leveling up), and clearly noted drop rates for the loot & Charms. These 2 items are the easiest to power your character at the beginning, but drop rates go from generous in early game to practically non-existent at island 5. It has potential, but even with the $25 buy-in - this game becomes an un-progressable grind at level 35-ish. Honestly avoid, and don't spend the money on the boosts.
