The game may have been "inside the box," but the concept definitely wasn’t haha. What an original and unique idea! It was really fun to see what you managed to do with the spinning-and-clicking mechanic. It added a nice variety of challenges that, despite being short, were perfectly capable of keeping me engaged until the end.
I really liked the animation you used to switch from one wall to another. Even though it doesn’t move the environment like in a 3D space, the start and end of the animation connect with the walls, which makes the spin to the left and right feel believable.
The art was minimalistic and gave the game a distinct identity. I'd even say it adds a certain sense of melancholy with the unstable lines, which, combined with the darkness around, creates a subtly eerie atmosphere. Maybe a background track with just one instrument would make the game even more immersive, though I think something soft to match the rest of the elements would work best.
Doing all of this in 6-8 hours must have been really challenging—congratulations on your dedication. With such little time, you managed to deliver something memorable and with its own identity. Even the most "outside the box" ideas can make a positive impact when executed well, like this one.
If I may offer an artistic suggestion to enhance the mood of the game, in case you plan to work more on it, the farther the box is from the player, the darker it could become. Maybe even a gradient effect would be enough to convey a sense of depth, making the environment feel more three-dimensional and elevating the user experience.
The Game Maker gang strikes again! Congratulations on the game, keep up the great work, and I wish you the best of luck in the jam!
