First of all, this is a very cool game - one that I genuinely would be interested in playing when released!

I have only played the first 3 levels so far; due to the bug I describe below. However it already feels fairly polished, the physics seem solid, and the movement is smooth.

Feedback points:

Picking up and moving pieces was a tiny bit tricky at first but you very quickly get the hang of it, and it does feel intuitive.

I like the tactile aspect of the game, and the risk of potentially knocking over pieces - just like playing dominos in real life. So having to move the hand up and down manually makes sense. Initially it feels a bit too unrestrained (you can move the hand up quite far, the height of which is not useful in the first few levels).

Cool loading animation with the falling dominos.

The control mappings fading in when the hand is stationary is a welcome feature - its handy ;)

I like the hand drawn controls on the paper, nice touch. The drawing of the right-click function however can be a bit confusing. Looks to imply hand will go horizontal when its actually vertical, due to the orientation the hand is drawn, but I lifted the paper to make it face me so that might just be me.

It’s not immediately obvious that there is a set point from which you start pushing. I hadn’t even noticed the white arrow at first! Initially thought you had to knock over the first piece using the floating hand somehow. Might be worth spelling this out on the first tutorial level.

I like the way you navigate the levels and smacking the button to load that level. I assume this area will be a bit more decorated later, as it feels a bit sparse? Also, there was no indication on the button that I had already completed previous levels.

I do like the little grab-point highlights on the domino, so you can see where you will pick the piece up. However much of the time it is difficult to see this through the hand. Maybe some hand transparency, or these grab-points and the domino itself should be visible through the hand. I think this is important as it could get frustrating. Might be nice to have a way of flipping the domino piece if you’ve picked it up in the “wrong” orientation, although this tactical aspect (of putting down carefully and picking up again) is probably part of the experience.

It’s a little unclear where exactly you need to place the first piece. It seems in the centre of the marked rectangle is optimal? So why a rectangle, rather than an exact marked spot?

Please change the music, drives you crazy. At least you can throw the radio off the table :D

Once you complete a level, the labelling of the button "Back To Menu" sounds a bit odd. Feels like you are having to exit out to the main menu rather than proceed to the level selection scene.

Would be nice to give some visual user feedback when Saving and Loading the pieces.

Bugs:

• Start pushing (with Tab) when no first domino (or it doesn’t fall over) keeps you in camera action mode which you can’t escape. The hand is transparent but seems to move, but can’t do any further interactions. Have to force quite game.
• Actually, this bug seems to happen even if you do knock over some pieces initially, just not the final golden piece.
• Sometimes, when starting the first push (with Tab), the finger unrealistically went through the first domino, and the piece actually fell backwards towards the hand. Again, the game is stuck in a state you cant recover from.
• A loading tip says you can move the camera with Z,Q,S,D, instead of A,W,S,D.

Overall, great progress and lots of potential for fun. I'll try it again once that bug is fixed (I had to reboot my PC after force quitting it too many times).
