Your first chapter has lots of action in it, and it also has some good descriptive language. I had some trouble following what was going on, though. I think the main reasons for this were: (1) the tense changes a lot; and (2) I don't have much context for the battle scenes. Perhaps you could go through the specific language and make the tenses more consistent. That would add to the readability. I would also suggest adding some information on how the characters find themselves at this point.
Thanks for your review! now, I'm active again, and the second chapter has been released! about your trouble following what was going on, yeah I also have that problem because the first chap is very action-intense, which was inspired from a minecraft animation battle. for the tense change, that's because i couldn't find the good way to describe what was going on, and mostly because grammatical errors. and yeah, the story is much a mystery for this time. and the Herobrine himself is supposed to be mysterious. I hope you read the second chapter
