This a highly amusing piece. If you're into reincarnation & comedy this would entertain you.
I liked the the pacing of the story as the author knows when to tone down and also when to place humour on some chapters.
I liked Karma's sass too. Sometimes Karma would just be chill and next thing, he/she/it would be a condescending companion lmao.
There are some technical issues that I bothered me as I read this.
First point, punctuation marks. During the initial chapters, I noticed some parts wherein the author didn't put any indications or marks for the character's monologues/thoughts. Although it was written mostly as a First person POV, the writting gets confusing as some of the narrative parts were typed out as dialogues and sometimes the dialogues are supposed to be internal thoughts.
Second, lack of vigilance in proofreading. This got progressively worse past chapter 8, as I saw a lot of run-ons, slight typos, incorrect tenses and active/passive voice misuse. At first, it was bearable, but as I get to the mid-end part of the chapter, I'm seeing those errors pop up every now and then. One of the chapters even had a character saying the word "wonder" instead of the word "wonderful" (context of the dialogue was the character is describing a good idea.)
Third, limited vocabulary pool. This by far made my eyes squint a lot. Sometimes I noticed that some words were inappropriately used- or more like the context of the word doesn't fit the scenario/dialogue. I can see the author trying to show diversity on his writing, but again, just by simply placing "synonyms" won't cut it. Another thing to note, I noticed that some of the expressions and dialogues get repetitive. (One chapter even had a paragraph where the word "deem" had been repeated 3-4 times)
I do recommend that the author should be vigilant in proofreading and utilizing grammar checkers. I think with minor revisions, this story would shine better.
