Simple but interesting, could possibly be expanded upon more lore wise and I'll admit I was a little confused on if I had to interact with doors to open them or not (eventually I learned to just walk into them). I do have to ask, do seven year olds swear that much? Haha, it was kinda funny but mostly surprising cause I couldn't think of the MC as a child with all that language.
Keep making games, keep coming up with more ideas, and make sure to have fun.
