First of all, thank you very much for your detailed comment. Your suggestions will be considered for the next games.
Actually, I had a very different monster dream in my head. But I couldn't find a teammate to model and animate my dream monster. If I could put that monster, the game would be extremely scary. But I had to find a free monster model.
I will solve the friction problem thanks to you. I didn't know how to solve it.
I have more games in mind. I hope to do them in the future. I will share it on my Itch.io account. Thanks for playing the game.
