It's just an April fool, no updates are planned.
I'm writing this review for the people that still don't get it: this is just an April Fool, no you can't unlock new Chara and no, is not gonna get updates. It's a shame I know because the game is solid and fun but what you got is already everything. Maybe in the future they will decide to turn it into a real game but until then, this is all.
