Su.IT, I tried the game and I have two fundamental grudges against it.
First, there's no clear direction I need to take, no hints about how to progress the game. When I click "Level" on the school's page in the journal, I get some general hints that I might need to do some things to advance the level, but there's no specific info about what's required to advance to level 2. The walkthrough on the wiki doesn't help at all in this regard. Maybe it's just a bug in 0.1.4C, but this is a showstopper for me. I don't want to blindly try everything and hope to trigger something which will allow me to proceed.
Second, my guess is - I might be wrong here, please correct me if I am - one of the things you need to do to advance is to have the cafeteria ready. Yet to even start working on it, an event has to happen. My grudge is, this event is a random one, you have no way of making sure it happens. It took me some 50+ save/load cycles before I got the event to trigger the way it has to in order to create the cafeteria. Nope. I can accept grind if - and only if - I have a feeling the grind moves me closer to reaching my goal, like even a failure improves my chances in the next try. A pure random grind - no, thank you.
And a bonus bug report for you: if you hold a PE lesson (at least at early noon), the time doesn't flow, so you can do it again and again, as many times as you want in a single day, bringing the stats up to any level you want, with the exception of inhibition which stops at 90.
