I liked it.

I liked it, it wasn't great, but as you said, you made it really quick.
Next time, take your time and make something better, I want to see what you're capable of.

I really like the concept of the game, but I found it super easy. The solution to all puzzles was to either go for the furthest key or go back and forth in the portals.

It's a really nice idea, but I think the level design could use some love. I see the potential of this!
