I think you're being too hard on yourself. Even if it's not exactly how you imagined it, your game is fully playable, has a definite ending, and is quite fun. Game jams aren’t about making a perfect game, but rather about experimenting with ideas. If you’re still motivated, you now have plenty of time to polish the game the way you want!
Your game is also quite unique—the fetch quest genre isn’t something I was expecting in a game jam. I could even consider it a Metroidvania since you collect objects to unlock new areas, and some items are even saved permanently (the ones in the safe room).
It took me about an hour to play from start to finish. I got stuck multiple times, but I always had something to try, and eventually, I found the solution myself. The only thing that bothered me was the slow walking speed, as there’s a lot of backtracking. Otherwise, it was really fun to explore the map, talk to NPCs, collect new objects, and figure out how to use them.
I also appreciate the little interactions for things you don’t necessarily need to do—like consuming air or water multiple times. It’s technically useless, but the fact that there are unique texts and even a special game over for each is a great attention to detail!
