It's not like they're random, you know. Those that don't depend on combat losses are avoidable by having basic levels at four stats or by choosing options carefully. Those that happen after losing combat are mostly not happening after the first loss, but only after the third. And you can just win combats if you don't want to get Game Overs anyway. I spent some time and learned basic build and money earning opportunities, now I can beat the final boss in about 20-25 minutes after the start of the fresh game. And it's probably casual walkthrough.
Again, the game needs challenge to motivate you learn its mechanics and have fun with it as the game. If you wanted to spend 30 minutes to finish it and see some main storyline, you shouldn't try games, play visual novels. Or read the text inside the game without playing it, look at the pictures unlocked in the Gallery in cheat mode.
