It was a funny read, and an entire refreshing concepts from the isekai protagonists from the get-go. I really like the concept, and I am sure that people would feel entertained too! Another point that I'd like to express is the usage of onomatopoeia. Although some parts (onomatopoeia) made it fun for us readers to read, writing them alone might sound unnatural since the novel is telling the sound and not showing it. if that is your writiing style and you feel comfortable about it, I supposed it could be fine. But if you plan on writing a formal novel, then showing those sounds and use our senses (as readers) that would be really fantastic.
