a little recommendation for the gacha thingy! idk if it's going to be removed soon but if it's going to be a permanent feature i think it would be better if there's more way to gain ticket other than keep logging in. here's some recommendation:
1. add mini game! i mean, literal mini game, since this app already took a lot of storage, it couldn't be a really serious game.
2. add daily mission, like review one game per day, like a certain amount of notes, etc.
