Comments on Grim Defender: Castle Defense for Android
★★★★☆Derek B.· Aug 25, 2025
Good game. One problem, though: you need to get to stage 40 at least to unlock the auto turret, there's only one, and you also need 10 dark gold (premium currency) plus 125 rubies plus 150k gold. It will take you forever to get that much dark gold, regular gold and rubies. You'll have to withstand the horribly tedious nature of aiming with your finger forever......unless you pay up, of course! Buy the one auto turret to give your hand a break, for only $30! (or spend days grinding).

I'm a returning player from several years ago. Lovely game, just wish the save/load system was based on accounts rather than codes
★★☆☆☆Jordan Dayes· Aug 7, 2025
Needs tweaks to economy values as its takes forever to get gold or black gems for upgrades its clearly pay to win

The reason I am giving this a one star is the lack of Dark Gold. It feels impossible to earn dark gold except through quests and bonuses. Please make the rate of getting dark gold a little higher than it is, because otherwise, it's going to be hard for your players to enjoy the game if they feel like they cannot progress or upgrade. It is fun to play until you need Dark Gold in order to progress

I like the game, but obtaining black crystals has gotten ridiculous. I received one from killing the level 620 boss and killed the level 630 boss 10 times and still no black crystal until I finally got the next crystal after beating the boss at 640. If you want to improve your game, you need to add more black crystals, especially if a player has the level 2 holy grail to increase crystals.
