Good, short term fun. It's a decent challenge, but it's also pretty easy to breeze through the free levels, and the gameplay is pretty samey, so it doesn't seem worth paying for to go on. I'll probably be uninstalling soon. Maybe the dev should release a free puzzle once a day or week to keep interest up.
Not enough levels It's crap that you can only play 30 of the easiest levels and then have to buy the rest if you want to keep playing.
Great! Easy to understand, interesting challenges!
Fun game Unclear at first that you can move atoms any where. Once to know this, it's a fun game.
Fun & Challenging! Just Got Started & Already Addicted To It :D
