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.

The last sign on the first level was accidentally placed in front of the sign telling you to freeze the fountains first, so that's definitely a mistake on our part. We're currently developing a way for you to more easily fall down (especially narrow paths) without bouncing up again as that's one of the biggest complaints about the game.
