I enjoyed this game, and can really see room for you to add. It reminded me of this game from years ago. https://www.kongregate.com/games/Hillbridge/fishy-waters
Good concept, but there are WAY too many hints. I solved almost every puzzle before looking at half the hints. The ones I couldn't place immediately I never had to return to.
Amazing game. While playing I received an error that unity was out of memory and the game totally froze. I had to go back to the beginning. The other change I would like is the quit button to clarify that it is save and quit (and even just a save without quitting)
Interesting - when the game quit - did you try going to the Saved Games menu - it should have saved the last room you got to. Actually quit - just quits - but the game saves your progress each time you enter a new room and you are right that I should make people aware of that (otherwise they are always going to be thinking that they will lose their progress when they quit).

Hah good catch! I remember playing that way back too and I loved its focus on more RPG aspects.
