I managed to win in like 16 days. This is an amazing game, it's probably one of my favourites so far. I also don't see an issue with the balance at all. I don't think it's possible to win on the first playthrough without understanding the game but I don't think that's needed.
Some slight QoL could have made this feel so much more polished like being able to delete mid-path, or indicators as others have mentioned. But please don't think that these made the game much worse, I really hope this game gets showcased.
