Total shit, i'l pass while it remain as is.
Puzzle gameplay and art style is fine though, but hscene texts are meh.
If you go with lootboxes, at least let them stack indefinitely and opening simultaneously. Or make it open in the moments you got chest.
No stamina - lie. Chest slots works as "stamina" system.
No pay walls - doubtful, considering posts from soft launch players.
And only one chest per time can also be considered as time pay wall.
