I was a bit unsure of the effects of the different items but it was fun to figure out a strategy to survive. My interpretation was to come up to the surface to heal on flowers then go under ground to continue exploring... I'm not sure if that's right though haha.
I did see the strawberry but it was a tile away and I just couldn't make it. The only downside is more of a nit pick of using "D" and "J" for dig/jump controls other than that it's a solid game. Well done.
