Alright, so, I'v e got a couple of ideas for newer versions of the game, now that it's become clear that FH IS in fact updateable.
I'm going to try and steer clear of ideas that would require the source code to update, and I'm instead only going to suggest things that I think will be possible to do without it based on what's been done already.
Anything marked with a "*" is something I'm not sure of whether or not it'd be possible.
-A world map to put somewhere on the forums, maybe in the 'help section or something. Just a drawn map showing the different continents, regions, areas, and etc., with game map and portal locations pointed out.
-Arctic/snowy regions, with things like snow-covered trees, frozen lakes, 'tundra' areas with small bits of vegetation, snowy caves, etc.
-A new parkour-ish map, maybe with instead of floating square rocks to jump from, its this huge tree or something to you have to climb up using parkour 'steps' such as branches or things lodged in the tree. Then at the top, there's a portal to a new sky map- maybe a city in the sky type of thing.
-Rainforest map.
-A desert map.
-Mountain regions.
-*Because this was achieved with a hack, I'm assuming this is in some way possible: Increased slider abilities, such as the ability to make bigger/smaller characters, shorter characters for stubby-legged creatures, etc. I mean, it doesn't have to be /too/ insane, like elephant sized or something, but just a bit of an increase would be nice. It'd definitely be useful for cat roleplays, so people could actually be properly sized kits!
-*New animations, not replacers. For example, paw licking, nuzzling, etc. And maybe change the name of 'Buttswing' to 'Moonwalk'.
-*New manes, tails, etc.(I'm honestly not sure if the standing mane was there before. I don't think it was and I'm pretty sure it's new... but I could be wrong. I'm suggesting this based on that bc I honestly don't remember that ever being there.)
ITEMS:
-Bandanna
-Claws
-If new manes arent possible, maybe mane /items/ that come in a few pre-set colors? At least it'd be something.
-Same idea as above, but with tails? I believe there is a tailless option, or at least a bobtail. Maybe they could be fitted to match the bobtail at the base.
-Tuft items with alpha planes for a furry look.
