recently I released casual fish game Frenzy Fugu Fish with 45 levels (there will be more levels soon). It is getting very good ratings and already there were few great reviews.
Just quick description here, because screenshots describe it better You are small fish and your goal is to collect all pearls in a level withing a time limit (usually from 1.5 to 2.5 minutes). There are various enemy fish, jellyfish, bubbles, ice, etc etc that threaten you. Sometimes you can use special powerup to inflate (as a puffer fish) and are invincible for short period of time.
There is variety of levels in three beautiful waterworlds - pure action, some logical, some maze, you will see.
Enough words, just play
