Hidden cats- seek and find

Why is there no “zoom in” feature for this game. The pictures are so small on an iPhone that you have to zoom in to find the cat faces.

Honestly, I downloaded this particular app thinking I might be able to print the images as coloring pages. Decided to give it a good, dedicated play first to review it. The first five or so levels are good background drawings with cat “stickers” on it (so I couldn’t use it for coloring). When you click on the cat stickers they turn green. So app works fine. Next five or so levels are REALLY basic drawings with SUPER TINY cat drawings in places. Even zoomed in you cannot tell what they are, you just have to tap on them and see if they turn green. Five second ads between levels so not intrusive.
