I'm very disappointed with this game. I played all the others and was excited when Brain Test 5 came out. I can understand tricky puzzels but a lot of these just don't make sense, hard to figure out. It doesn't get easier it got more complicated as it goes along because you only get a limited amount of tries and then when you loose lives you have to wait a certain amount of time to play again. Because I don't want to loose lives I'm watching a bunch of ads to get clues. Just very frustrating.

I finished level one, and now I'm being asked to "Please tell us what you thought of our game!" Well, based on that one level, I think it is cute, runs smoothly, and has potential. I clicked 1-star and submit, but it didn't take my submission so I came here directly after trying more levels. There are not only banner ads attached to the app UI, there are mini ad spaces showing more ads inside the game levels themselves, plus forced fullscreen ads at random intervals. Avoid this game.

Hey, thanks for the thoughtful review and for noticing the potential. We understand that multiple ad placements and pop ups feel overwhelming, and your feedback helps us improve the layout and timing.

I thought with the name, it's just gonna be harder puzzles unlike other apps like this but no, the 'hard' they're talking about is it's 3x game per level. Same game but 3 different solution every levels. I didn't get to enjoy the game further because when I go back to offerwall I'm playing why I installed this game, AyeT studios didn't tracked it. I've been playing for 30 seconds and more, that just made upset even more. Thankfully, I checked before continuing because it might be like other game

Thank you for the detailed feedback. The offerwall tracking is handled by AyeT, but we understand this felt frustrating. We will also review how we present difficulty so expectations feel clearer.
