Very creative puzzle mechanics, you really pulled a nice use of the theme, congrats! I took me a few minutes to realize I had 2 hands so I could carry 2 cubes, maybe an indications of that could be a good idea (Or maybe I missed it lol) I had a good time, enjoyed it and how I needed to think to solve the puzzles! I like the art direction, I can see the assets were made quickly or by not very experienced people but it does the job for a jam. (It reminds me of Star Wars Imperial ships interiors) though the lighting is a little poor, not very clean rendering. Audio is good, and the music is great and didn’t feel too repetitive, nice job!
Though I found it frustrating not to be able to look up and down, weird choice, also a high Field of view could have been handy or an option to change it, and a slightly higher jump along a sprint key, but that’s maybe just my preferences, in terms of ergonomic navigation in your 3d space.
