this is good
This is the best of the Shift series. It was really really really well made and polished.
My issue was with the levels, the first 15 or so levels all seemed like they were just tutorial levels, they weren't puzzle oriented at all, it was just going through the level. I was starting to feel like quitting, since there was no challenge.
Then the puzzles started to come, and the difficulty curve went up waaay to fast. Its like it went easy as hell the first 15 levels, then the difficulty just sky rockets.
It's a great game though! I am really happy to see you move the series in a different direction. I hope to see more like this one in the future.
