It is too easy to miss stuff in this game, you get three missions that all need to be completed in the morning, doing one of them causes the other 2 quests to vanish so you can't progress those characters. You try to do a mission in the evening and a new mission triggers in that room instead so you miss the one you were doing. I've had the quest that needs scotch tape for ages but it's not available to buy in the store because I've missed a trigger somewhere and I can't get past 28% completion without starting over.
I love the art style and the game itself is interesting but the code needs some serious tidying up, I don't like having to rely on walkthroughs and cheats. (Probably some hyperbole in this post out of frustration with being stuck for the past hour)
