One of the most good Games that i Play out there! I am in Gacha Hell for many years and if we are talking about Gacha games with a very Friendly (F2P peeps is a meh but i dont mind them) and Jiggling mechanics then this is one of the games that can make your day smile. In aspect of Play style,  its very simple and easy to Understand,(Specially if you know how to read) Art style of characters are top tier and the only grind here is less stressfull (items and leveling Mats).

The game is amazing, the music is just the best, the gameplay might not be everyone cup of tea since it is a tower defense game, the story is phenomenal, the early chapters is not that good but the mid to later chapters is just amazing also even the side story is if not the best story in the game. As for the characters they're all amazing the art and design is just beautiful, even the low tier units is still usable for the later contents. Now for the Monetization, the game is pretty free to play friendly since as mention before even the low tier units can still be usable, the game gives quite a lot of resources and when events drop they give free pulls to use.

such a fun game! the gacha element isn't too painful even if you're f2p and the gameplay is pretty fun, my only problem is the adventure leveling, it just seems unnecessary to have to wait or pay to continue
