### 3/5 — Pop Up Adds

*2024-11-21, version 2.2.4*

What I can play, I like.  But I am going t have to delete.  The pop up adds are covering the game and I am unable to play.  And when Google removes it, they are replaced with Google saying they removed it.  And then you have the Google message covering the game.  Aaaggghhh!

### 5/5 — Under the deep sea

Love this game. Fun to play.

### 4/5 — Great game

*2024-03-09, version 2.1.9*

Only gripe is the trophies are buggy.  I just finished level 52 and all levels are 3 stars.  While I have the trophy for clearing level 50 I don’t have the trophies for 100 or 150 stars even though I clearly have that many stars

### 5/5 — Love this game

*2023-10-08, version 2.1.5*

But. When I win the games it's not giving Me any tokens even when I watch ads for bonuses it doesn't ad Them on. Please Fix.

### 2/5 — Good game but lots of glitches

*2023-06-29, version 2.0.4*

Very good game and not too many adverts but can’t get past level 2159 as the counter fails so doesn’t count down the items as you get them so very frustrating.

### 4/5 — Levels

*2023-06-15, version 2.0.4*

Will there be any new levels after 2400? I’ve finished them all and am hoping for additional levels

### 5/5 — DL3回目🐬

*2023-06-12, version 2.0.4*

時間制限なし、何度でもやり直せる、アイテムも何度でも使用可、行き詰まりすぎたら見かねて助けてくれるwたまに連鎖しまくって勝手にクリアさせられるw自分にピッタリのゲームです。面白いし時間を忘れて夢中になりすぎて全クリしてしまい、もうDL3回目ですがそれでも楽しめます🐬たまにグロい他ゲームの広告と、最近は凄く長い美容系広告があるのが難点。でも本当に面白いのでずっとサービス提供し続けて欲しいです。
