Um. Hard pass.
Level one was semi-interesting. Decent graphics for a free app. But levels 2, 3, 4, 5, 6, 7, etc. are literally ALL the EXACT same thing. It’s literally the exact same level and scenery over and over again (the map/graphics don’t change, difficulty never changes, etc. - it’s Groundhog Day! - same level repeated over and over and over). They change the goals/challenges.....but it’s mostly the same two or three, just in rotation. And YES....with ads EVERY few minutes. It’s not bad to look at or play for 5 minutes. If you’re interested in investing more time than that, it’s probably because you’re brand new to technology and this is your first game ever. Don’t waste your time.
