Like the other commenter said, the feel of the controls were actually fairly good, but it was certainly confusing getting the gist of the game.

The description at the beginning didn't make immediate sense and I had to restart to go read it when I started getting stuck. It is an interesting idea and a competent execution though (fast move speeds, clear indication of the capsules state). There are some bugs with resetting and the lack of description or screenshots makes it really hard for anyone to want to download. Highly recommend adding some information to the game page that describes how to play.
