the game worked great for a little bit.. then, once in a while would crash when an ad was playing.. now I can't even finish setting up my units for the round, because every time I get half way through watching a few ads and placing everything on the board.. it'll crash in the middle of one of the ads and reset all the progress I just made. it's entertaining and I want to keep playing but if I can't even set up the units I need for the round with out it crashing, I might as well delete it..

Too many unreliable ads in the mix. I understand the design to incentivize ads. For a few weeks this worked fine and I didnt understand the complaints. But then I started getting ads that had NO progress bar and the X never appeared. So I'd force close the game and re-open it, only to find I had to start from scratch. So I tried not watching ANY optional ads. Died on wave 3. This was repeatable. So you need ads to actually beat levels, and the ads hang and cause you to fail levels. Awesome. Not.

its fun so far but has a huge bug I've never had with any other game, the format is messed up, I think because of the ad bar during the game ,it forces the position of the screen up and a good 20 to 30 % of the screen is cut off. fix and I'll give you 4 or 5 star depending! gladly
