this looks like a great game but it lags a lot on my end, im not sure if its a bug or just my phone but there needs to be an option to lower the quality so it runs more smoothly. I was able to fight 2 monsters but it was really hard to get the timing right because of the lag, and everytime i tried fighting anything since the countdown gets stuck at 3 or 2.

Seems to be a good game, but the constant vibration is annoying an drives down my battery super fast. Will reinstall if theres an option to turn off vibration. Edit: The haptic feedback no longer drives me nuts, but it's a fairly beefy game and takes up a lot of my battery and doesnt preform super well on my older device. Wonderful work you're doing though, and I hope this helps in some small way.

Shockingly well made for a free game, and made to support a fantastic cause! If you love the ocean and the creatures that live in it, odds are you'll love this game. Keep in kind, however, that due to the quality of the graphics, this is clearly a game intended for higher-end devices. I believe that the developers will be able to optimize it with time to run better on all devices, but for the time being, expect semi-regular lag unless you're on a top-of-the-line phone/tablet
