Many errors and the truth is a waste of time, the only thing that can be saved are the CG, it is seriously a shame because it has a good base and if I had polished the errors and added 2 or 3 more things and delved a little more into the plot they would have had a better game.
Honestly, I feel worse about these types of games that have something special unlike the typical hentai rpgs on the page, but that don't finish developing it.
P.S: I just read that there is an April update that fixes a bug in the store.
