The game is really amazing in every aspect right now (minus a few). Every upgrade and monkey base you create is meaningful. You build a sense of attachment to the bases you decide to invest in, and you learn to pick the right upgrades at the right time. Everything is literally earned and no monkey or building is taken for granted. You could be grinding away on tracks to earn cash or methodically planning visits to reap full banana farm value. Building arrangement matters, and quests are plentifully to the extent that they are always possible to complete. There's a pvp system and event interaction as well. Overall, Kiwi did a great job, and I hope even more from Bloon Monkeys :D
Oh nose!
