fun unique tower defense game, only problems are the 'no ads' power up activates automatically, and when you do get ads they last a long time. additionally, sometimes the ads don't have a skip button, but instead force you to go to the app store, which resets your speed powerup(which also takes an ad to activate). To summarize, it's clever and has unique mechanics, but the ads need to chill out. Also it seems that they're using AI to respond to the reviews, as every response is the same.

Hey Mustafa, thanks for the kind words about the game! We’re testing ad settings, but every ad should have a close button, even if it opens the store. Please send a short video to support@playscope.io so we can check it and help if something is wrong.

So far, I like the game. It's challenging but not too hard and the gameplay is smooth while graphics are good for what they are. That being said, where is everything? at what point does it unlock what is locked on the home page? When do I get to see anything like the comic on your game page? Unlock and fix this and I will adjust the rating.

Thanks for the detailed feedback, Chris! 😊 Some features unlock as you progress, and we’re also working on adding more content, including story-style elements. We’ll keep improving the home page and progression clarity. Hope you’ll enjoy what’s coming!

Fun, but lots of ads and progress stops at level 100 and won't let you progress any further.
