Crappy
Easy, too precise (the best time possible is like, 26-29 seconds and you're asking for 30 for the best medal, which is ridiculous, but possible), crappy collision, didn't allow for WASD (this is EXTREMELY important - some keyboards cannot press two arrows at the same time)... 1 audio file, decent graphics, and only 1 level.
Better luck next time. I know you can make a game worth playing. This sucked.
Medals:
To get the best completion time you have to beat the "game" perfectly. Start by running right into the ice, then as you slide back hold left and jump right as you reach dry ground. You should land on the first raised area, then jump and land on the third, shorter raised area, and continue left until you slam through the door.
After getting the key hold right, time your jumps to land on the short raise area, then the farthest right raise area, then the first ice platform, second ice platform, then switch area.
From the switch, hold left and go back across the two ice platforms, then fall and run into the farthest right raised area. Hold right and continue across the ice at full speed. Push the bottom box until it drops. Run to the question mark, then turn around and jump to the second level.
Push the middle box off to the left, then fall on top of it. Press left then up really quickly so you have a tiny bit of momentum to reach the platform up to the left. Then run and jump to the right, push the third and final box down, fall on top of it, get enough momentum and jump the gap.
Secret medal: wait for the clock to reach 5 minutes.
