Damn good, very replayable (I usually turn sound off and listen to a podcast while playing!), just needs a tweak to use less battery. It's neck and neck with the Android OS! EDIT:Cloud saves of achieved accomplishments/completed goals are also needed. Need to start ALL OVER AGAIN if you uninstall and reinstall/install on another device!
I loved this game for years, but in the last month it has twice deleted all of my awards, upgrades and levels and reset me back to level 1 with nothing. All gains lost... 2 times. Unacceptable. I'm done. Don't waste your time, you spend hours in the bathroom with this game at work and then it erases all of your accomplishments.
This game crashes constantly on galaxy s8+. Game runs a few levels then crashes. The level stays the same but progress is lost. It used to be a decent game but now it really sucks. I'll be uninstalling and waiting for an update. Devs please fix.
Update. Love this game ever since I installed it on my galaxy s3. Recently started crashing and figured it was the end as it's an old game that hasn't seen an update in years. To whoever fixed the crash bug and took the time to update this game in the play store; thank you! You're my hero! Always liked tower defense games and for me this is a good one. Nice progression of difficulty and some fun challenges for achievements. Haven't regretted paying for this once, more than I can say for many apps.
Good game, always take a couple rounds each day. Bust today it stopped working on my phone and tablet. Cleared cache, uninstalled and reinstalled even removed backup file and nothing helps.
Was unhappy that recently started constantly crashing. But the developers fixed it. So I'm thrilled to play again! Love this game after so many years. Would be nice to get a Robo Defense 2.
Fixed fatal crash on app start.
