Spoiler ahead..
I got the RISE! medal by running my penguin into the ground and boosting until I'd accumulated a big pile of snow. Additionally, I think if you hold down the right arrow and the boost along the ground, you gain points for "diving" into the sea.
Found a bug. I managed to get a skill on a hero above 20 without using items. I wiped my hero's memory (reset stat points) while I had unused experience. I maxed out a stat at 23 (no items equipped).
This game moves too slowly, even for a turn based card game. It takes forever, then your opponent quits before you win anyways. The only way to win is to get the +1 cards right off the bat..... so largely luck based, the strategy is extremely simple.
