Comments on Planet Defense: Space TD for Android

★★★★★ Ivan Vujica · Sep 10, 2026

Enjoying the casual strategy play, ads are tolerable

★★★★★ Terry Brown · Sep 13, 2026

I have played this game and its predecessor for quite a while now and find it quite enjoyable, I had wanted to skip all the ads so purchased the VIP package, which makes the game simply fun without a chore. The only gripe is that the price of the VIP pass was equivalent to that of an AA game produced from a large studio, I think perhaps a more reasonably priced offer would be a VIP pass to a bundle of these devs games to offset the initial outlay, just my economically minded opinion.

★★★★★ Raymond Papera · Oct 24, 2026

I have played similar games, this one has the nicest graphics, but the hardest version to play.

★★☆☆☆ john aragon · Aug 31, 2026

Changed my review to 2 stars. I've progressed to level 20 almost without paying anything but the grind is tedious. The adds have increased and loop... the worst of it is you have a 50/50 chance that watching an add restarts the game, and you lose all progress on whatever level you were on. That killed it for me. Add that events are pay to win, and coop levels never match you with a player equal to your level or picks cards specific for that level... physical or electric or energy and so on.

★★☆☆☆ Tavish Feagins · Aug 18, 2026

Do you enjoy watching ADS? Do you enjoy 10+ weekly and monthly battle passes? Do you enjoy no progression unless you watch even more ads in game? This game is for you!

★★☆☆☆ Deadpool 25K78 · Sep 4, 2026

Generic really, and you can't even get x2 without paying a subscription. Not even a permanent thing. Disgusting.
