Loving it but as someone else said, you really need a save. :) I spent a couple hours creating and getting the hang of the game but finally ran out of time and as much as I want to dive back in today, not saving is a bit of a drawback.
The controls, a tutorial (if only a pop-up at the start that says how to grab and place things would be very helpful - if nothing else on how to pick up and view the datapad's help). I finally was able to get the datapad help up and read it (the reading it up close took a long time to figure out yet it so simple once you know). It took hours just to get that far. Sad ... I know since I live and breath computers. :(
The flow, the feel and potential are all just perfect. It's not so chaotic that you are stressing on every little detail and you can sit and watch a game you create. I think when you get to music and background stuff -- being able to choose your style would add so much -- it's already got a great ambient rhythm to it.
I can't wait to see more.
