Hey, thanks a lot for the suggestions! Here's a breakdown of where things stand:
1. The hardness of each zone is actually shown when you hover over the zone name (except for Air). I did consider showing the value directly in brackets next to the name, like you suggested, but I worried it might be a bit confusing for new players, and adding a label like "Hardness: X" would take up too much space in the already cramped bottom corner. That's why I ended up going with the tooltip approach for now, though I'm definitely open to revisiting it if a clearer solution comes up.
2. This behavior is actually intentional. There's some specific code in place to keep the slippery effect on the last row of Stone, but remove it on the last row of Ice. The idea was to make it feel more natural. Sliding on Ice makes sense, but sliding on Granite felt off. Effects like regeneration freeze are kept strictly within the Ice zone. That said, I totally get how it could feel inconsistent or confusing to have Ice effects behave differently depending on the row. Maybe it's something we could ask the others how they feel? Should we keep it realistic or less confusing?
3. Yeah, this one's tricky. Moving the Settings and Info buttons to the top isn't ideal, since that area's already packed with resource counters and the Back to Top button. It could also lead to misclicks. Shifting them slightly to the left could work, but might look awkward, especially in fullscreen, where the fullscreen button disappears. I'm leaning toward adjusting the itch.io game window height so the fullscreen button appears below the Settings and Info buttons instead. That might be the cleanest fix.
Thanks again for the feedbacks, these are definitely valid concerns, and I would be happy to know what everyone thinks.
