Great puzzle game! I enjoyed playing it a lot, and some of the puzzles were really great!
The riddles was really good, probably my favorite. I knew most of them, and it was clear lateral thinking was needed, but it was super fun nonetheless.
The cube puzzle was also really good. Having to bring it through a portal is a great idea! Though maybe a hint that you can do so is great. I got it fast but idk if many do and it could feel too difficult. The second part where you have to drop it was great.
Maze was fine, but that's about it. Mazes are cool ideas but one that everybody is used to, so adding something to spice things up could be good. You could add traps for example, or something that follows you. Just going through the maze can get boring. You know you'll solve it, but doing so amounts to walk around and a little luck (or just turning right/left at every turn)
Platforms puzzle is straight unfair lmao. I'll leave my thoughts cause I think it's important for puzzles. There's no real indication to know if the next platform will kill you or not, or what it will do, simply forcing a restart of the whole thing. It's not even entirely clear if that's was supposed to be happening. I jumped a couple times to the middle platform simply because I thought I was clipping through it / missing it and not that it was intentional. It only became clear once after many tries that I took another route and saw it happen again. At that point I understood, but the frustration was already there which is bad for the experience. There's one platform that straight up kills you. Some way of hinting that could be good, maybe it could glow red or something that signals danger. Lastly there are the platforms that grow smaller and smaller. I tried to jump before it disappeared to the next one and I could never manage to do it, it was always too far away. I was gonna say the platforms were uncoordinated and it couldn't be solved! Much to my surprise, the platform instead of disappearing simply goes back to the initial size. You could for example have them continuously change sizes, not jump from small to big and not just when the player is there. That way, we know that we have to jump on it and try not to fall as it gets smaller, and jump when it gets bigger. Things like these that you can't predict make it hard for the player to accurately know what to do. The best part of this puzzle was the last one, where you had to grab the block and place it to jump across a big gap! I understood what my ability was, and found a way to use it to pass the test. That's what it's all about!!
I really liked the experience! I wrote a lot about that puzzle but don't get it wrong, this was a really delightful puzzle experience :). More puzzles like the riddles one and moving blocks would be amazing, I reaaaaally liked those. Congrats!
