The Good: I liked the rhyming. It reminded me of Zecora for some reason. Also, the evolving was pretty well done though I'd have liked to play a "eat whatever's smaller than you" game without being a fish for once. The music was okay, nothing special but not overly annoying either. Finally, the OM NOM NOM was funny and a nice touch.
The Bad: Sometimes it's tough to discern what's larger than yourself, since things are of different shapes and sizes. Also, when you die you can still move. I hate that because it breaks the suspension of disbelief and just looks stupid. The rhyming seemed a little forced at times, and the example I can remember best is the one between "malicious" and "finish". In what universe do these two words rhyme? I know how hard it is to find rhymes for things, having had to write in rhyme in my life, but if you can't think of a rhyme for something, NEVER force it. It becomes, with all due respect, painful to read. The concept of the game is a little overdone, but instead of adding something new you seemed to stick to the script of being (or turning into) a fish. When I saw that there were 10 generations of evolving, I kinda expected something that would leave more of an impression than a cookie-cutter turtle thing.
The Fatal Problem: THE BLOODY FLASHING. IT'S ANNOYING. TURN IT OFF! Caps lock aside, this is a Fatal Problem that could turn literal. There's no seizure warning, plus it's unexpected because it doesn't begin until the fish level. Seizures are at their worst when faced with a simple pattern for a while, then faced with sudden multi-coloured flashing. I don't even have epilepsy, but I feel like this game could single-handedly give me it if I play it enough. Nevertheless, I now have some eye strain from playing this. I'd ask you to put a warning in the description, but why even have the flashing in the first place?! There's no reason for it, and it comes right the f*ck out of nowhere! Turn it off!
Conclusion: Washed-out concept, not very much potential, even worse payoff, bad rhyming, and the worse case of unnecessary flashing since the Exhibitionists' Convention of 2012. AVOID THIS GAME.
