The best tower defence game I've played, The characters look nice and the lobby UI is cute. I just wish that you can access your online progress to offline and same with offline progress being able to be transfered to online since I'm usually outside. I wanna access my chimera lord and other characters offline, the hourglass too. But overall this game is best for time killing and the satisfaction of clearing it is amazing! I highly recommend this to anyone who likes strategy and TD games.

I love playing this game either on online or offline but there's a problem and it's the fact I started with offline and didn't realize I couldn't link my offline data to my online data. I know there's a reason for this but I hope there is something that can help me cope with that. And also when I'm playing on my online data I sometimes forget to switch to offline and so times when I don't have Wi-Fi I can't switch it to offline. Other than the two minor problems this game is very addicting 😀

It's a weird game- it took me a game or two to get it, but once it clicks, it clicks. And at first, you find it easy, but the difficulty tiers *drastically* increase the mastery required by the player, until it reaches the point that you have to have a basic knowledge of all creatures and possible events in the back of your head. Wonderful game, would advise.
