After a while, it's very repetitious. And the best weapon can't be obtained. You can't buy it or win it. The game gives you free trials of each weapon, and then offers to let you buy it for $7.99-$9.99. Except the only one worth buying. That's not available. I'm on Level 5240, BTW. Also, it isn't true that buying a weapon removes ads. If you want more than a very small number of points for beating a level, you must watch ads. And it often crashes without giving you the points.

I thought, I'll see how my grandson likes this. It wasn't so bad. Then,... when you're given a choice of 3 boxes to choose from, hoping to get the 700 dollars at least one time, from choosing first, out of the 160 levels you've beat, you're still having to go through 2 more boxes before ending up with the 700 dollars, surprisingly on your last choice. I'm not going to watch him be upset from the game kicking off and rebooting. If 700 can't be given just 1 time first, forget it.

The game repeats a few variations of the same levels over and over. There are a lot of guns, but you earn very slowly and will have to play dozens of levels to earn decent ones. Ads are of course overwhelming and seen longer than 30 seconds. One odd glitch... I get to demo the rocket launcher, but never get a chance to buy it. I might actually pay for that one.
