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!

The loved the idea! My biggest wish would have been for a cute voice actor to voice robochan and have more dialogue throughout the game. Would give totally Portal type vibes!

I liked the first part of the game with guiding robochan via constructing pathways with the tube pieces but I felt like there could have been more use for the multitool as the only times I really felt I needed to use it was to break the blocks in the 2nd stage of the first part. I agree with another user that the second part of the game felt very different from the first part and I personally left the game wanting to do more with the concepts of the first part of the game than the second. I also feel as though the first stage on the first part was a little vague in what it wanted the player to do as the only instructions were to open a simple box so I toyed around a little bit with its lock thingy but like 4 minutes later I saw the funnel and realized I had to get robochan into there as per the tutorial. I think the box instructions are confusing and lessening the amount of interactable objects in the scene would give the player a better idea of what their goal is as oftentimes I wasn't entirely sure as to what the objective was. Another concern with the game which is just really nitpicky is that this game is very easy to cheat, placing my hands though a door, I can teleport past the puzzles and to the exit. In addition to this, I could avoid the puzzles in the first part by taking a tube, putting robochan into the tube then carrying the tube to the funnel and dropping robochan. I really liked the mechanics for platforming with robochan and if you continue this project I would love to see that explored further as there's tons of potential there with obstructed paths, different interactable objects, etc. This was a good project and had passionate work put in but I just wanted to give as detailed feedback as I could in case you continue working on it!

It took a bit of time to learn the mechanics, however you did an amazing job with this game. the level of detail is astonishing, the cute little robot ball is my favorite part. i can tell that a lot of time was put into this and i think that if you worked more on this game it could even release as a game on steam. great work

That second part is a bit of a break from the first bit, but I finished the game and had some fun :D Hint 3 was below my floor btw, I figured it out though ;)

Great game! Loved the concept and fits the theme very well.  Only suggestion I have is to prevent the hands from colliding with the physics or getting altered by the speed portal, since it makes it hard to teleport/move when the hand is being pushed away.
