We went with a very similar mechanic although we went a different direction with it. You definitely nailed the very portal-esque feel and the first puzzle with the card icons was a great combination of ideas. Like others have said, having to press the button for power was tedious especially since you had to wait for it to recharge. I also frequently came across weird geometry situations where I would clip on the corner of a wall or I kept sticking to the first boxes puzzles so it was hard to jump up them originally. These were fairly minor issues though and the core concept is really well done. Nice entry overall!

Thank you soo much for playing my game and also for the feedback. I also see your submission, it is looking good, downloading it now.
I already made 6-7 types of scaling objects but due to shortage of time, couldn't make a puzzle out of it. I use only 3 different scaling objects in the game, those are the basics once. Some completed scaling objects aren't used in the project.
You managed to do quite a bit with just the three objects so I'm sure the rest of them would make it even better too. Definitely the time crunch doesn't help get those ideas in though. We wanted to add a couple more challenges to ours too such as fans that would push the player in different directions but we had to scrap them in the last stretch.
