There are great bones on this game and I think you should keep refining it. There were quite a few fiddly, frustrating interactions. For instance, I had a lot of problems with the 'lip' some of the portal holes have.
I really like that while I couldn't quite understand the totality of the mechanic, the design of the levels let me 'feel' its character in each scenario. Again, really cool stuff! Looking forward to more from you.
