Hey Thanks a lot for the feedback, i initially planned much more features for the portal mechanics, but due to time i did not implement that much of it.
The last level was a scrap from that, it feautres a "green portal" which is different from the yellow one, it does not switches places with you, but you can still move crates with it.
Unfortunately, i did not do the introduction level to this mechanic so the last level is a bit unsettling because of this, i left it as the "bonus level" for the jam, but maybe i should have pushed a bit more for introduction to green portal.
I wanted to use no text in game too
