I love game, super fun mechanic! Two things I'd say for the future - 1. In the first area with the areas that move you in one direction, you may want to not allow people to put a second portal where the arrows are, you they will 100% do it until they softlock themselves to see if they can; 2. and this is super nitpicky cause when a game is fun that's how I get, but beepbox music is great, but it always has a tendency to be a pretty short loop when all is said and done, I always find it helpful to spit out a few similar sounding tunes and intermix them to give it a bit more variety (also definitely subjective though!). Sorry for all the words, but i can't wait to see what you do in the future!
