United StatesGreat concept, so many tears
We paid for the full version, because I love that we have a soroban abacus adventure game. My child often ends up freaking out because it crashes a lot, or because the ticking bomb sound effect warning her that she’s running out of time, or because suddenly at level 32 it gets inexplicably difficult with no tutorial anywhere. On level 32 we go from adding one digit numbers to suddenly adding 77s without discussing “friend” of 77 and I didn’t do abacus as a kid so I’m trying to help her with pencil and paper and it just keeps tick tick ticking and she’s sobbing because now she hates abacus. Please offer a way to disable the timer, please add a tutorial for level 32 and please fix the bugs causing it to crash because there aren’t many other abacus game options, this could be a real hit with so many kids out of school.
