The last sign on the first level is extremely misleading. I had no idea that I had to enter the fountain to freeze it. In hindsight it makes sense, but I though that the game was just unfinished. Otherwise, I thought it was fairly enjoyable. At first I thought the bouncing was a really nice way to do wall jumps without making the player figure out what combination of keys and actions did it. But I found that it was a bit of a hindrance because you always bounced upwards, even if you are falling down. It was also a bit challenging to go back and forth between being not slippery and slippery.
