wow, really cool exploration game! the game really sets up the portal mechanic well by having you chasing the dog only to end up back in the start utterly confused xd. the level design is low-key peak, with the labyrinth you're exploring feeling complex while also not feeling too overwhelming for the player to explore imo! the size of each "puzzle" segment feels just right, it helps that each segment kind of locks you into a relatively small space through the use of recursive portals until you eventually find an alternative portal to allow you to exit that space, avoids the risk of players feeling too lost, nicely done here! each puzzle's solution feels so smart and clever, really encouraging exploration and outside-the-box thinking, no joke i'd audibly go "ahhh" after i managed to find each solution, its so well crafted!
the visuals make the labyrinth feel so big and vast while making the player feel so small, which makes it all the more satisfying once you reach the end! i personally liked the game being low res for what it is, it reminded me of the original Myst look, though this is just my opinion xd. there wasn't really anything that required any detail to be shown to the player since a lot of the things you looked at in the game are relatively big in size and have strong shapes and silhouettes, so i could personally see the game taking on this low res look if you want to it to be stylized that way! also the lighting is really good as well, like the different colors used, added a nice variety of tones to the scene!
this was a really cool game, i enjoyed seeing what challenge each new area would bring me next! great work!
