I’ve had no problems playing without Wi-Fi, and haven’t had to deal with any ads unless I would choose to connect for power ups, etc. I’m over level 100, and although a little repetitive it’s still fun to play. One problem is that for the last few days the “hero” addition hasn’t been working, but the space it would take can’t be filled by a spawner, so it can mess up planning shots. Also, if the brief “coffee break” pops up while I’m merging spawners they freeze up and I have to close out the game to get them to work or be able to move them. Other than those bugs I’ve really enjoyed the game

Love the game. Going to have to look for something similar though because the app won’t load anymore. I’ve tried multiple times a day over the last 14 days or so. All of the games from this developer require wifi (can’t put on airplane mode). So this is one of those games I can only play while watching tv. I wish the levels were longer so I can merge to higher numbers. That may come once I get to a high level. But with the app not loading and sitting at a black screen I guess I’ll never find out…

Don’t bother with this app unless you want to pay for no ads, which I didn’t stick around long enough to figure out if you could. I don’t know if I’ve seen a game with more frequent ads. I usually don’t mind ads that much since you have to make money somehow, but the frequency makes the game not worth playing. Calling it a “coffee break” doesn’t make it less annoying to deal with. The concept of the game is fun, and I would play it for sure if I only had to deal with a few ads per level, but there’s an ad about every minute and the levels take multiple minutes to beat. For that reason I say don’t even bother downloading this one. Move on and save your sanity.

This game can be enjoyable once you get past all the ads (thank goodness they finally added the option to pay and bypass the ads), but it seems that every little bit, something in the game breaks. For a while there, in late July and most of August, you couldn’t move the hero around because it wasn’t clickable. It was fixed with the advent of the second hero, but now that my second hero is leveling up to lvl 3, my first hero has lost all of its skills. Please fix this new bug. Thanks
