The premise is very nice. I always love a mind-F game like these, imagine pairing this with a portal-like puzzle and also dimensions that enlarge and shrinks you while you walk pass them!
However the movement feels a bit clunky, especially the slow falling. The lack of jumping can feel frustrating at times too. It could use more background to make each area stand out more and to indicate the loop.
Love this game and hope you continue to work on it. Would love to play a full release! Feel free to come and rate my game as well.
