Wow, that was a great game. I love the simple pixel graphics, and the level design was amazing. I love how the levels go from easy to hard well, unlike in most games, where it usually stays the same then leaps. The levels are really hard though, but don't change that, that's good

There's only one problem-The controls are a little fidgety. It's hard to move well, because if I press right, let's say, it moves too much to the right, so I quickly have to press left in order not to fall down into spikes.
Other than that, though, great game. Keep it up.
