I've seen similar games in this jam as I have expected, however each brings something new and interesting to the table. In your case it was a bunch of things like keys and portals. I believe you made it in unity and I noticed you have common issue where character can stick to the wall if you press into it. To solve it you can just create physics material, set its friction to zero and apply to the player character. I used that bug to cheat a bit through some levels, but even so the puzzles were real nice and additional elements create a real nice challenge.
