I liked the minimalist look of the game. The sound effects were the best aspect of it. Obviously, some music would make a good addition. The lack of friction made it tricky, but it was nice being able to just cling on to the side of the platforms. After a while, you do get the hang of it. Some more level variety would be great.
Overall, it was fun.
