I don't usually give negative feedback, but man, is this game - at least sandbox mode - just a massive bugfest. From everytime you sleep you have a message error to the Tora loop when she goes to school with her new uniform, I can't make an exhaustive list of all of them.
Storywise... I won't say anything, the bugs drove me away from the story. But some mechanics are more than weird : You can buy power, 50 for 1 coin but 100 cost 5 coins and 200 cost 10. Yeah, I'll buy 250 for 5 times 1 coin, thank you. Corruption stats ? Using this option doesn't decrease your power and I can't say what the stat does anyway... I won't list everything here, but it looks like trying to put many mechanics in one giant pot and waiting for it to work by itself. Less mechanics but used more efficiently would be better, at least imho.
The best advice I can give to the dev is choose one mode only, story or sandbox and stick to it until it is in a clean and solid bugfree state. Then only, if it isn't too time consuming that it pushes updates back later and later, introduce the second mode.
I'll come back in 6 months-ish to see what the game turned into, hoping to see something where the story can be enjoyed (if it's enjoyable, honestly I can't even say right now because it is such a mess , at least in sandbox mode).
PS : Before you ask, yes, I did install bugfix BEFORE playing the 0.3.5, so all the bugs I saw are there despite the bugfix.
