1. I think jumping/movement is fine, especially with higher levels and this is a video game still. With castles in the sky, cat people, evil creatures ready to eat your face, etc. I honestly plan to add another skill after a couple levels where Prince lands on his feet in a few instances. (Nothing like falling forty fear or falling off a floating kingdom... He's screwed then haaaah)

2. Mounts- final, I think land mounts should be near the start, but flying mounts should be later on and earned. Or we get butt ugly mounts at first then have to quest for better ones.

3. As for health bar, I had a rp that kept a system and put it in each post so everyone knows

Example

HP: 100%
MP: 100%
Status Effects: Paralyzed, Attack Up
Level: 4

[u]Inventory[/u]
Gold: 100
Wooden Harp: 1
Cinnamon Cookies: 10

[u]Enemies[/u]
Wolf 1 Level 2: 50%
Goblin 1 Level 5: 75%

And yeah xD
