There's a lot to like here. Specifically how well polished it is! Very well done there! I like the steady introduction of new mechanics, and the extra little things you did to give different pieces of the game juice. Rotating portals, character squishes on moves, the buttons your press pulse, cleanliness of the art style.
The only two things that tripped me up were:
- I like the idea of changing up the tiles (they're not all perfect squares, some have cracks), and maybe this is just me, but I was weary of those tiles at first, thinking they'd fall out from under me.
- I struggled with the controls in regards to the portals. It was very easy for me to go through a portal, pop out, and move a space, all in, what felt like, one button press.
Other than that, great job!
