Finally got to try it! Awesome art and gameplay puzzles! I wonder if an alternative control scheme could work with swiping to shoot the portal, since the turning control was a bit slow to get used to. Also maybe making the portal stop when the player releases finger (rather than tap again)? This might feel more intuitive, and I think would have made the exploration-based levels less cumbersome for me.
Also it would be super cool if there was a level that made use of the recursive portals, like maybe a wheel that needs to be cranked so if you set up a looping portal it'll help you win.
