I honestly like how the renders and the girls look, the story started well, but little by little it went downhill, although it went up and then fell again, but from there everything is fine, The Devil's Layer and earning hearts to advance and the rest becomes tedious and repetitive, that's why I recommend removing the sandbox or implementing a linear mode and sandbox mode and Give the player the option of how to play, many DEVs do it this way and players prefer it too, so you can experience both and choose or just choose the one you prefer.
Without further ado, I'm waiting to see if it's going in the right direction, and I hope it is, don't abandon it, because I also tried the other game and it had potential and looked good.
