*update: it has been a couple months since I downloaded this, and I have just completed everything. There is really nothing else to do in this app, unfortunately. I have enough space on my phone so I'll keep it and see what updates come out. But overall, unimpressed with an app that feels unfinished."
Progression slows way down after you get the first remote island. You need to obtain 6000 gems to obtain the second remote island, and obtaining this many gems has taken me over three weeks and I'm still not there. In the meantime, there is absolutely nothing to do, as I've leveled up everything else that I possibly can. Leveling up animals seems pointless because they never change and they don't do much to progress your game. I also wish that the animals moved, especially the fish and the shark, which just look dead. Also the instructions in this game need to be better. I had to figure out on my own over time what all three skills do because the game doesn't say. Anyway, I like the game and see potential, just needs some work. Keep updating!
