犬とコレは簡単

Amazing! & suggestion

I saw my friend play the game and I helped her a bit. Two days pass and it’s today, I wake up and get the game. I’ve been playing progressively throughout the day and I managed to get to level 56! The game is really addictive in a great way

Though I wish you can look back at previous levels to see what kind of puzzles there were. I spoke to my friend again and she said she was puzzled by level 46, I wanted to look back and see what it looked like again (cause this was over call)) but sadly I couldn’t

It’s a great game though, I wish more people would know about this 🧡❤️

겜은 재밌으나 말이 안됨

주간랭킹 1등 점수가 4455점. 나도 정말 열심히 해도 400점이 한계. 3등. 당시 1등이 700점대. 말도 안되는 속도로 점수가 올랐는데. 이번주는 더 말이 안됨. 그래서 리뷰 별 2개 깍음. 10월 11일 오늘도 1등 한번해보자고 결제까지 하면서 했는데. 1등은 한시간동안 1분에 한판 하는 속도로 2시간 내내. 가능한 건지 모르겠네요. 쉬운판만 있는것도 아닌데. ai도움이라고 하기에도 너무 빠름.

Response from developer

안녕하세요! 즐겁게 플레이해 주시고 의견까지 남겨 주셔서 감사합니다. 🐹 주간 점수는 한 판을 깰 때마다 쌓이는 방식이라 플레이 양이 아주 많은 분과는 격차가 크게 벌어질 수 있습니다. 다만 비정상적인 기록은 저희도 정기적으로 점검하고 있으며 말씀해 주신 이번 주 상위 기록도 확인해 보겠습니다. 소중한 의견 감사합니다. 🌻

Love it.

Perfect for colorblind players.

Response from developer

Hi! We put a lot of care into making the board easy to read and comfortable to play for everyone, and it sounds like that effort paid off 🐹 Thank you for the feedback, and we hope you keep having fun with it 🌻

Light touch

No matter how lightly you touch to exit out it sometimes takes the touch as a double touch and then you lose because the app is screwy

Response from developer

Hi! Thank you for reporting this, and we're sorry a stray double touch cost you a round 🐹 A single light tap registering twice is not how it should work, so we're looking into it. If you notice where it happens most, such as right after a popup closes, letting us know through the support contact on our store page would really help us track it down. Thank you for your patience 🌻
