SpaceChem Mobile

I played much of this game on my desktop, but it got very difficult to solve may puzzles. The concept and execution is impeccable. I would not recommend it for anything less than a decent tablet. Graphics would be way to difficult to see on a cell phone. I want to play it over on a portable device with the knowledge I gained from previous play, which was many hours. Requires great logic combined with imagination. If you struggle with the demo, I wouldn't recommend the full game, even at the very reasonable price.

Love this game on the PC so I had to get it for my tablet too. What makes it good are the simple rules and open-ended solutions to all the puzzles. Only wish I could use keyboard shortcuts, or at least more easily place instructions on the board. All the instructions/speed controls are at the top edge of the screen and are difficult to select on small screens.

I've played the game briefly on pc and loved it so I downloaded this for my Samsung Galaxy NotePro 12 running Android 4.4.2. Crashes 99/100 times on startup. The one time I managed to run it, I got to the last tutorial level before it crashed again to never load again without crashing. I've re downloaded and reinstalled, but still not working. I'll gladly change my review to 5/5 once this gets sorted out.

Not terribly optimised for tablets, buttons are tiny and hard to hit when there's tons of free space on the sides of the screen that could be used for bigger menus and buttons. Work that out for easy 5 stars.

Extremely enjoy this game on PC, however, when I bought the app on Google play, a few buttons don't work i.e. "show menu" and "show tool tips". You need these to save reactors for future puzzles, unless you want to redo the molecule sequence all over again, which unnecessarily time consuming. Will switch to 5 stars when this is fixed.

This has happened twice now- in the middle of working on a production puzzle the bonders just stopped working. I restarted the game, deleted and remade the reactor, nothing works! Those 2 levels are now unplayable. It's really aggravating especially since this was my favorite game.

This game made me time travel; unfortunately forward only. Today I started this up on PC at around 9AM. The next moment I remember is 4PM, when I realised I'm hungry as hell (fortunately, I had plenty of water to drink at hand). This is the first game to achieve this in a long time. The backstory is nice (although has very little to play with the game itself). The controls are a bit small on my mobile, but still usable. The puzzles are sometimes hard, but you don't have time pressure on you. If you are into puzzle games, you should definitely try this one.

I've played over 100 hours, and completed all levels on three devices now. Would have been worth my money at $30. Very challenging pure logic game with an excellent difficulty curve!

I enjoy this game a lot. I would recommend anyone play it, however the mobile version isn't very good for mobile phones. The buttons are small, and some are at the top edge of the screen causing my notification bar to appear when I select them. A UI overhaul is necessary.

This game is one I love going back to. There is such a sense of accomplishment when you improve a system by even just a few cycles. *update has fixed Samsung loading issue. Works fantasticly again.

Samsung Galaxy tab s2 wont start up at all. Gets to loading screen then stops

You really need a screen at least the size of a tablet to play this game properly. Dragging pieces from the top brings down the top bar, the text is tiny, and the game seems to think you have the ability to right-click.

Crashes if undo button used and occasionally for no apparent reason. Fortunately, since it continually saves all my creations, it is only a minor annoyance to reload the game. Using a Tesco Hudl2.

Was crashing on my new Galaxy Tab Pro 10.1 (while working perfectly on my Note 3 and older Note 2) but the latest update fixed everything. A truly brilliant game that I come back to time and time again.

At first I thought the touch controls were bad, but as I played more, they are great.

Premature optimization is the root of all evil and hella fun game play. I just wish the controls at the top weren't placed where they activate the Android notification pulldown.

Fantastic game, but not meant for anything other than a tablet. UI is really flawed for smartphones, but the core, addictive gameplay is still there.

I have a lot of fun with this game, but it's very difficult to play on a small screen, and it drains my battery incredibly quickly.

Would be 5 stars but crashes alot, never lost progress so not a big deal. Amazing game otherwise! Love the difficulty. Makes me think

This is not made for mobile devices. Tablets maybe. What a poor halfhearted showel ware.

Great game but I can't see anything on a phone and it's tough to touch anything on the top of the screen.

Great game and deserves 5 stars, but has issues. On Nexus 9 game does not run in fullscreen and has black bars on left and right sides of the screen.

love the pc game, having it on mobile is awesome. Crashes on startup consistently when disconnected from the internet though, please fix and then it'll be worth 5 stars from me.

Most fun I've had in a mobile game in a long time. No stupid micro-transactions. UI could use a little work but I'm really enjoying myself.

The first time I played it it ran fine a day ago now it crashes just after loading the start screen. Galaxy s5 I do not think the problem is on my end :(
