Hi, I tried the web version of the game. I didn't think much from the first level but it did serve as a good tutorial. Things really picked up from the second level, it was a really nice surprise. It was fun and challenging and the music really got me into it. I got past that level but the 3rd was just too hard for me with numbers coming vertically and horizontally.
One thing I would suggest is adding a video of the gameplay to your store page as its hard to get an idea of what the game is about just from the screenshots.
Great job.
