Piranhas failed to amuse
Well first off you didn't even tell me how to play the game, huge minus. You didn't even bother to tell me "move over things rapidly back and forth to eat them". I spent the first few minutes of this game just trying to figure out the key to make my fish feed, and actually had to take a look at your "walkthrough" video just to figure out that much.
Not that it mattered since the game itself played like a blimp you painted green and drowned in water. Never have I seen a fish 'eat' and swim back and forth without physically changing direction, nor a fish have the elasticity to bounce farther out off a sandbar than he was initially.
And just leave the game now if you want a frame-rate beyond 12 or so, you won't get it. The game just can't process itself fast enough to look any better, no matter how low you put the graphics down. Level 3 was kind enough to tell me I had a boost feature: what they didn't tell me is that if I ever wanted to use it it would be on a 5 second delay from click to boost just due to the game's own shortcomings.
Unplayable. Just unplayable.
