It looks great for sure. Had some bugs with movements sometimes "sticking" and character moving/turning multiple times (painful near plants) and also with big plants attacking through the walls, though that could be intended.
Health for sure is a limited resource here and its quite difficult to balance both it and oxygen at times, though worst culpit for me was this bug with movement.
Other than that and visual ui bug after you revive (you see fruits counter not refreshed until you pick up new one) - game is smooth and nice! Great theme too!
