Being honest I am not that interested in tower defense games and I only play 2 so this is one of them. This game is actually better than I thought. The gacha system is ok, the characters is all really nice in their own right. Their designs and voices are all fitting and good. This is actually a fun tower defense game and the bgm and sound effects are all also fitting and nice to listen too while playing. Although it can get real hard sometimes its still a good game with awesome events!
