In this game you play an engineer, designing the interior of reactors in order to combine elements into molecules. It requires a lot of logic. The order and timing of each reactor setup is completely up to you. The better the timing and setup, the better the score. Excellent replay value. As i learned more, I found myself going back and re-designing earlier levels for better scores. The ui is tough, but manageable on tablets. Not for everyone but definitely a gem for some.
I love the PC version and really, really wanted to love this one, too. The interface is just SO BAD, though. Whenever I'd drag an instruction from the top of the screen, my phone's info bar would pop down and obscure the available commands. The method of swapping the colors of instructions is just bad, too, and amounts to "hold down this on-screen button that's closely nested between three other buttons while tapping precisely with your other finger." Ugh. I'm glad I didn't just buy the paid version sight unseen.
Great game, flawed interface. SpaceChem is really fun game with a heavy focus on logical problem solving, but it continues to confound me with its illogical interface design choices. I played this on both my fairly small Galaxy tablet and my very un-small Galaxy Note 2, and the microscopic lettering wreaked untold amounts of havoc upon my aging eyes. The fixed aspect ratio also doesn't help its case either. All told, if you really want to enjoy this gem, seek it out on other platforms.
Font too small The app looks promising but the letters are too small to be read hence make it unplayable. My screen size is 3.5 inches.
Zoom perhaps? Seriously 5 pixel high letters are not enough on a high resolution device like a Nexus 6. It needs simple pinch zoom to make it at all playable.
Awesome This game is wonderful. Not many levels but this is a demo and I'd gladly pay for the rest of the levels. A little hard to understand though, even after the "tutorial" levels.
Fixed a crash when loading on newer Samsung devices.
