I liked the music, the animations, and I was impressed by how many levels you managed to make! I had trouble at first because I didn't understand the portals only need to be activated once, and after that can be used freely. Because of the resetting back to the stage beginning, it felt like i had to play very cautiously and slowly to succeed. I got to the second stage, but started to feel frustrated around this time. I stopped after using a green portal and popping out right on top of an owl :(
I think I would have enjoyed it more with either less backtracking or more respawn points. Great job completing a game in 2 days!
