The complete idea is very nice, I just want to say a few things that could improve your game:
Penguins with "powers" or "items", some kind of flying enemies, hmm, yeah more.
It would be adorable if the penguins that are on the floor were animated, something like "help me", "help"
1. I was considering powers, but didn't have energy/time to actually include them. I wanted to create something simple, fast and push it out....well, didn't expect "simple&fast" would eventually mean over 2 months of developing
2. Good idea. At the concept phase, they were supposed to scream "Pick meeee", but I thought, I'd become annoying. Hmmm....I might include it in an update.
How about controls? I have one report from a girl (who doesn't play games at all), that it's hard. Decelaration and acceleration of the penguin is too week. Did you have any problems with that? Picking up penguins and coins, avoiding ice platforms?
