This is a comma splice and is usually considered a fault. However, it is usually acceptable for an informal writing style for short, connected actions. Example: "He got up, he drank some coffee, he went to work." https://en.wikipedia.org/wiki/Comma_splice [excerpt] In English grammar, a comma splice or comma fault[1][2] is the use of a comma to join two independent clauses. For example: It is nearly half past five, we cannot reach town before dark.[a] The comma splice is sometimes used in literary writing to convey a particular mood of informality. Otherwise, it is usually considered an error in English writing style. [end excerpt]

Dear Salvater, It is a run-on sentence, and that's why even the native speakers have this grammar point in their high school lessons. it is a mistake and needs to be avoided if one wants others to consider them good English users.

Yes it's a run on. but dont worry about it to much from English speakers. Grammar isn't most people's strong suit.
