It's an interesting concept. Keeping in mind that I don't typically like playing puzzle games -- they're just not that fun to me -- I think that the early levels were too easy, and there were several instead of just a couple. I kept wanting it to build on the difficulty, then the difficulty ramped up, and by that point I was struggling to keep engaged. Again, not really a fan of puzzle games. Overall the sound design was nice, but I didn't like the "hurray" when I finished the level. I just found it oddly jarring to hear a voice when up until that point, there was none. I think you could add a little prompt with the cinematic that lets people know that you need to click to advance. But I did like the graphics and that cinematic is a nice touch, maybe needs a key sound effect playing when you advance the story tied to what is being shown. Apart from that, when the bunny moved, it was not that clear it was hopping along, especially when moving down stairs -- it looked like it was just lerping position and not animating. To be clear, I do think there is an interesting puzzle game here, I'm just not your audience.

This was super interesting to play.  I like the style, reminds me a lot of children's storybooks, but AI think it fights against the Rubik's Cube that looks pretty generic. Changing up the colours or edges might make it look more coherent. 

I think at times it does get a little difficult because of the need to continuously spin the cube around, so having an option to give a hint or guidance, it would be useful. As for the spinning mechanic itself is well done, but the way the player interacts with the cube could be improved, for example, clicking to zoom in and out, and being able to drag to solve, rather than having to click buttons. 

I think the biggest thing that would be important to implement is being able to jump rather than having it done automatically. I thought it was pretty awkward that I wasn't able to jump being a rabbit, and it might introduce some alternative ways of solving each puzzle. 

Overall though, I think that this was a really cool way of approaching a puzzle that incorporated a Rubik's cube. It was really cute and had me thinking for a few levels^^

This is a wholesome, fun and family-friendly puzzle game.   I love the story and how you tell it with pictures at the start - also, I'm a big fan of the hand-drawn art style. The music and sound are excellent. The bunny's voice adds to the charm of the character. 

The game controls felt intuitive. I liked how the first few levels were simple, and the more complex controls / moving the cube around were introduced later to ease the learning curve. I appreciated having the option to restart the level and that the camera goes back to the player when returning to 2D from 3D.

In terms of difficulty,  I found some very simple to solve while others took me a long time to figure out. To make the game enjoyable for more people, you may consider adding optional hints/tips.  

I noticed some of the levels had both a regular egg and a golden one. While I decided to stick to just the regular egg, having them there adds a bit of curiosity and extra challenge. I love how you give players the choice of which one they want to try to get - and still let them continue on with the regular egg. 

Something I felt was missing is a strong sense of progression. After solving many levels, I wondered, how many more levels are there? To better set players' expectations, you may want to consider ways of communicating this. Such as adding additional information to the start of the level when you show the title, "Ruby's Attic: Up the Stairs (level 1 / 15)". 

Even though it's mentioned that you can hit ESC to go to the menu,  for my first play, by the time I watched the story and played the first handful of puzzles, I didn't remember what was written on the "how to play" screen or itch page  - so didn't realize that there was the menu (and level select screen), until going back to the read the itch page to see if it said how many levels.  

Since the title screen only shows the level selection option if there's saved data,  other first-time players might miss this as I did. I would have liked more guidance around accessing the menu and how many levels to expect. For example, perhaps the first thing shown after the story is the level selection screen, so players learn that it's there and see up front where they are in the grand scheme. 

Suppose you feel that right after the story would interrupt the flow of things too much. In that case, another idea could be to show the level selection screen upon solving the first puzzle. When the player selects the next level, there's an opportunity to tell the player about the menu screen (similar to how you currently tell the player how to press space to go into the 3D mode).

Overall very fun, cute and polished game! Well done :-) 

Really cool concept & the visuals are really cute. Using a rubiks cube as a base for puzzles offer a lot of possibilities in term of level design, which you exploited really really well in the later levels.

in terms of feedbacks, it's hard to think of something that haven't already been said bellow. ^^

My main feedback would be that the controls to rotate & shift the cube only with the mouse is a bit frustrating, making it painful to solve some of the levels where there is a lot of rotations involved. I feel that could discourage most players to go forward in the game, though I have no idea how you could go to improve that part given the large number of inputs that would be needed to control the whole cube with a keyboard or controller (or even just a face). Maybe using both stick of a controller to shift the sides of a face would make it more pleasant to handle but I can see how it would be complicated to handle also.

I also felt that the first levels to introduce how the game works felt a bit too easy & they were many of them. maybe cutting some of them to go faster in the interesting puzzles would be a good idea. but that might be a matter of personal preferance (so don't take only my word for it). Once the first few levels done the difficulty progression is pretty well balanced already. some puzzles could be swapped to make it even more smooth but mostly I didn't really feel like there was huge gaps in term of difficulty.

The sfx and the music are nice. Though I would lower the music a bit by default so you can hear the sfx a bit more.  (the click on shifting a face is a satisfying touch)

All in all, It's a really neat concept for a game & with a bit of polish and rework around the contrlos it has a really good potential. Great job :)

the game is so cute! from the art to the music and the sfx.  the gameplay offers a lot of possibilities for level design and i see that you have tried exploring these possibilities extensively. i had to stop after cliff diving but i will definitely return to finish the rest of the puzzles. great job!
