The film had a low profile opening across Tamil Nadu on 24 May 2019. A critic from Deccan Chronicle noted "the director has to be commended for taking a new storyline and executing it without much confusion", and "though it was touted to be science fiction, the way it has been treated in a light hearted manner without many jargons and a crisp run time of 110 minutes makes it a delightful watch."^[4] In its review, The Times of India gave a negative impression and wrote that "the plot, which has scope for an intriguing thriller, goes haywire from the word go."^[5]
