Rahul Desai of The Hollywood Reporter India stated that "It is silly, campy and perversely enjoyable and Come for the crocodile, stay for the humans." Bryan Durham of Variety India writes in his review that "As much as that 145-minute runtime irks you, you get it. You’re on board with Nambiar’s vision all the way to the intermission and a bit beyond as well, if I’m being honest. But films of TYM’s ilk work better with tighter pacing. It already does a lot right. If only the self-indulgence could’ve been reined in." Rishabh Suri of Hindustan Times gave 3.5 stars out of 5 and said that "We don't see a lot of films like Tu Yaa Main being attempted in Bollywood and this one commits with sincerity." Abhishek Srivastava of The Times of India rated it 3/5 stars and stated that "The film keeps you involved while it plays out, but if you value narrative cohesion, you may find yourself wishing the two halves had merged into a more unified whole." Anisha Rao of India Today gave 3 stars out of 5 and said that "Tu Yaa Main is a gripping thriller that fuses modern romance with edge-of-your-seat survival drama in Mumbai. With strong performances and a twist-filled story, it keeps you hooked, capturing fear, trust, and high-stakes tension in every scene." Bollywood Hungama gave it 3 stars out of 5 and stated that "TU YAA MAIN is a decently made survival thriller that benefits from Bejoy Nambiar’s slick treatment, effective jump scares and sincere performances by Adarsh Gourav and Shanaya Kapoor." Shubhra Gupta of The Indian Express gave 2 stars out of 5 and writes that "My tip: Skip the first half, and check into this survival drama just in time for the crocs and the chaos in order to clutch your Valentine. If you feel the need to." Mayur Sanap of Rediff.com also gave 2 stars out of 5 and observed that "Tu Yaa Main feels rather indulgent for a survival drama. You can see where it's headed, and it just grows tiresome after a point." Hardika Gupta of NDTV rated it 2/5 stars and said that "To be fair, the second half is where the film marginally redeems itself."
