The Five Elements concept is really compelling — using elemental powers for environmental puzzles feels like it has a lot of design space. The idea of each element changing how you approach the same puzzle is the kind of thing that keeps players experimenting, which is great for engagement.
A few thoughts on your itch.io page:
Screenshots/GIFs on the page itself: Right now, visitors have to download the game to see anything. Adding 3-4 screenshots or a short GIF directly on the itch.io page would massively improve conversion. People browsing itch.io decide in seconds whether to click "Download" — visuals are your biggest lever here.
Describe one puzzle concretely: The features list is clean but abstract. Something like "Use the Water element to redirect a waterfall and power a mechanism, then switch to Fire to melt an ice barrier blocking the exit" — one concrete example makes the whole concept click instantly.
How do the Five Elements interact with each other? Can you combine elements? (e.g., Water + Fire = Steam?) If so, that's a huge selling point worth highlighting. If not, how do you keep the progression feeling fresh as players unlock more elements?
Browser/Mac build? Right now it's Windows-only, which limits your potential feedback pool significantly on itch.io. Even a short browser-playable demo of one floor could drive way more engagement.
The tower-climbing structure with escalating complexity is a proven format (think Celeste's level progression). Curious to see how you handle the difficulty curve — do players unlock all five elements gradually, or can they experiment freely from the start?
Good luck with the development! The concept has real potential. 🏔️
