Honest review, not fake. Read please🙏🏼

I am a very very attentive person and your game is the first to have depth, incremental aspects, idle factors and many more descriptive attributes. All games require a pay to play or they have the income/prestige system set up so you never achieve anything worthwhile and you’re always working harder as time passes not easier. And that’s pretty hypocritical of an incremental game nowadays, but your fake hits all the good spots and the game setup, design, layout, etc etc etc etc is perfect. Great job thanks for the update 4 days ago. Others and myself thank you and your team! Thanks for the entertainment as the world is going through this scary change..... 🤝

Dev if you’re reading, I’ve always wanted a multiplier for the people who watch ads for the bonus coins in a game but devs never consider this. How about each time the video bonus coins comes up after a round we watch it you give us a permanent .01 or .1 multiplier per video. So if I watched 10 videos I would have a a permanent 1x multiplier if I watched 38 videos total I would have a 3.8x multiplier. Just giving examples to give you the idea better. I’m not a good at explaining. If you put this in I would be very compelled to personally spread your game via social networking to help out somewhat. Thanks again if you read this

Developer Response ,

Really thankful for your great feedback and happy that you love our game. The multiplier is an interesting idea... maybe in a later version! Greetings, your Grim Defender: Castle Defense team ;)

Games very fun and addicting but not to the point where you HAVE to play like a lot of games are becoming. Practically no ads unless you watch them for unnecessary but helpful bonuses and there is ALWAYS something to do. Levels get progressively hard but never to difficult and there is an endless mode to farm currency if you get stuck. Loads of upgrades and weapons/traps/spell towers to choose from to better fit your play style such as ice, fire, lightning (personal favorite) explosive, rapid fire, shield bashing, and the good old all arounder.

I highly recommend give this game a spin if you like any sort of strategy, rpg, and tower defense games. It is very well rounded to suit any type of player.

Developer Response ,

Thank you for the great feedback. We really tried hard to create a fair balance between progression and grind. Happy that you like it. Greetings, the Grim Defender team ;)



Great game I love everything about it...
Update: I’d like to see if the devs could possibly do something about having an easier way of getting dark gold especially for the ones that don’t spend money into the game I know that I can get it from playing endless but it’s a luck kind of thing on that one .. there’s gotta be another farming method for dark gold if you could possibly do that in next update? That’ll be awesome thanks
