Yes, but you have to consider that this game is:
A. Fan Made.
B. Episodic. So, one can assume things will be different. As, there are many differences between this game and a traditional Pokémon game. I, actually have preference of this game over the traditional games due to the more mature setting.
Had this game not been episodic, and had this game been played via handheld like other Pokémon games I would have saved much more frequently. It's a matter of, I can leave it running for an indefinite amount of time on my PC while remaining idle and not having to worry about batteries dying or recharging.
It's not an issue of taking responsibility away, as much as it's an issue of it being different from a traditional Pokémon Game. Every episodic game that I've played had some form of auto-save or a save prompt at the end of the episode.
My issue was after I ended the episode it simply went to black. I had assumed I would get an opportunity to save at the boat after the preview. The warning after battling KiKi, does indeed tell you the episode will end. But, my concern is it says nothing about the state of your save. It simply tells you to go about and do things if you want to before the episode ends. I had implied by browsing about and seeing frequently that with each episode your save is preserved, that it could have saved for me or prompted me at the end of the episode. Not to mention the warning also somewhat implies the episode will end and there is no going back, which could lead to one to assume it will save there and prevent any progress or prompt you to do so.
As I've also said it doesn't bother me at this point, because I know. I'm simply pointing out that this is an issue for people new to the game, and there could be a form of miscommunication for them as there was for me. It's not my game, so it's not my place to tell someone what to do with it. However, I can make suggestions and give feedback. Do as you will, I've made my concerns present.
