Hi there, thanks for the feedback! Glad your enjoying the game so far. This project is still in its very early stages as I'm expecting at least another 3 years of development so my answers here (and really all my answers) are likely to change and evolve as the game develops.
Last time I checked the 'constricted' or 'grabbed' status effect SHOULD be removed as soon as you knock the enemy back or he's knocked out of position from any other source. So if this is not true then yes that's definitely a bug as knockback is intended to be the main counter to these effects (besides avoiding it in the first place.
Right now during Alpha and for the upcoming Web Release, races are not being worked on at all and will in fact be disabled for the web release. Balancing this game has proved to be pretty tricky and with all the changes to combat, character development and map generation I'm trying to focus on Humans only. The plan is to readdress races once the game reaches Early Access on Steam and the base Human game is reasonably balanced, refined and tuned.
A skill, items or racial abilities that reduces food consumption is definitely something that is possible in the future. I am hoping though to get the balance to a place where most players would likely find this unnecessary and would opt for something else to spend points on or equip in a slot. The Hunger mechanic is intended to just be a bit of a 'push' to keep the player moving and fighting efficiently. Its not supposed to feel like a ticking doom clock that's constantly pressing down on you.
I think I'd be quite unlikely to do anything to remove the movement penalty from Ogres as I feel like this is pretty fundamental to making them play distinctly. In my mind, the races are the place that I'd like to introduce these kinds of drastic changes to the base game play and to give the option to remove this sort of defeats the purpose. I'd rather buff up the Ogre in other ways while maintaining the penalty in order to make the race play more distinctly.
Like I said, this is all subject to change. Please feel free to offer up any other suggestions, critiques or just loose thoughts that pop into your head. This project is frankly far to complex at this point for me to keep entirely in my head and hearing what other people are thinking is immensely valuable to me.
