I played your game and my gameplay was in slow motion due to my potato laptop not being able to handle even the lowest of graphics but the level design is insane. I had fun playing the game and solving the puzzles. This might be similar to portal but I can't tell because I've never played it before but have seen other play it.
I do think the AI talking to you through text is not my favorite. Probably a robotic voice over would be better. I guess you can do voice overs when it comes to exposition and storytelling but when it comes to tutorials like displaying UIs and what to press things then visuals would be better.
Overall, fun game. Great puzzles and level design.
