As stated before the game is a gacha game. The game provides you with a free 10-pull for hero summons. Then after that, you have to either pay with paid gems or use summon controllers to summon
more heroes. The same goes with weapons except the game does not give you a free 10-pull for weapons. The summon controllers can be awarded by completing quests, but if you want to you can very well spend money on gems to summon as well.
The controls are pretty straightforward. I played hooked up to the television, so I played with the joy cons in a controller sense. You can also play in handheld mode, just not in touch screen mode, which
makes sense as the game did not seem to have an auto battle system in place, at least not one that I could see. So you have to manually go through the levels.
When it comes to leveling
up, you earn crytals that you use to level up your characters. The amount increases as you level but the crystals come pretty frequently, so it's not a problem. These crystals are different from the gems that you earn or pay for. When it comes to equipment
you have to set up your equipment before you go on your adventure, as you are only able to equip when you find things on your adventure, but not switch equipment out during your adventure. You have to pay attention when this happens because the window to equip
your gear is rather small, and you may miss out on equipping gear that could have been helpful.
