What a great concept and execution! I really liked the graphics; the portal animation was particularly cool. It would often take me a million tries to execute any given manuever, but that's just my lackluster platforming skills lol. The controls were a lot more intuitive than I thought they would be. I really liked thinking through how to get through a level, as well as the moments when it finally clicked and the satisfaction of successfully carrying out a plan of action. I also think you did a great job with the progression! I really felt like I was able to ease into the game and learning how it worked.
I really enjoyed this game! Great job!
