I really think the concept behind the puzzles in the first 2 rooms is great and takes full advantage of being a VR game.
The final room felt more like an escape room, which is not necessarily bad and I see you had to fit more of the multi use tool theme in there, but I really wish I could see more puzzle rooms like the first 2.
I love the graphics a lot too! If I had to give what I think could be a point of improvement, it felt a bit too busy with bright colours to me personally, and I wish the interactible objects would pop out a bit more, since at first I was struggling to tell at a glance what I was supposed to pick up and move around, and what was just static set dressing.
Overall an amazing job!
