does the full game have keyboard prompts, a move counter on-screen, undo, reset/restart buttons on-screen, and checkpoints for every screen? none of these are in the demo, but that's pretty old, and when I moved on to the second screen on level 2, resetting the checkpoint put me back to the start of the level because the first checkpoint is several screens later. also, how many levels in all and how many have timed requirements? I won't bother with those but I wonder if it'll make my life more difficult, ...

At least the very first one, "Rookie". Completed first level with all 6 orbytes earned/found - achievement haven't popped.

Any suggestions for similar games?

Is this game still coming out?
