It's Frustrating that on quick match pvp it finds matches that you need upgrades to fight. It should find someone that you can actually fight at your current level.
Game really needs more water-based towers... For one thing, there are many levels that are nearly impossible with the limits, and for another, a good 1/4 of my map is water... and I have nothing to build there, having hit the buccaneer and water wheel limits long ago.. Alternately, some sort of raft and pool, such as you could buy in previous bloons TD games, would be really helpful for a lot of the maps.. otherwise good game, just.. really hard..
This is a great game, and it's not demanding. It's not like one of those CCGs who have 'Limited Time Only! (Come Spend $100!)' kind of game. It's not one like *if you do not check every 18 hours you will lose a card t another player permanently*. It's a kind of game where the only thing you're really missing is the oracle who only gives a few and maybe a card, so you don't miss much. It's an addicting game and you have a hard time finding stuff to spend here (At least I do) and that's what I like about this game. Simple, and free.
