I tried to play through the game to reach some kind of ending, but it seems that after the appearance of the second copy of the character, nothing else happens. The atmosphere of the game somewhat reminds me of Undertale, which is certainly a good thing. After defeating the squirrel in the forest, I was given some items, and it seems like the shadows stopped dealing any damage to me at all. At least they haven't done so even once. Also, the game on the second TV is bugged. The second number is displayed the same as the first. But it seems like everything works inside, and rewards are given when you correctly guess higher or lower.
And also, it's a pity that you didn't make all the new items interactive. It's also really tiring to fall into the pit over and over again.
