First thing, the font was very hard to read!
That being said, interesting entry! I was very, very confused during the first loop but things started making sense in the second one. I think removing the limited time mechanic would be an improvement. I was able to build the portal once, it got too expensive for me after that...a little unbalanced, but that's to be expected from a jam game. All in all, I enjoyed my time with this one.
