I didn't expect much from a puzzle game made in a game jam, but this was great! The graphics were clean, UI did what it had to (especially the little key counter, I don't know why I loved that so much but I did). The sound effects and transitions between levels were great, and the little beeps for each turn was great. I loved the design of the spikes and the crossing mechanic was an awesome thing that I've never seen before! Quite possibly my favorite part was the fact that the name is a portal reference, and then there's the one level with the colored portals in them, I enjoyed that a lot. The only critiques I really have are that it could've used some music, and that the first level with the armored enemies is a little bit confusing to understand (once I saw the level title I immediately got it, but i was confused for a little bit). Great job!
