Here's a small update, to show off the prototyping for stamina: Every time you deal a strong attack (kicks and stomps) you lose a bunch of stamina which you will slowly regain, over time. However, to instantly refill your stamina, you can always have a little snack!
Now, there's a concept you'll know from other games. Just keep an eye on the placeholder UI, in the bottom left corner:

It's working pretty well already, so now I have to try it out a bunch and see how it feels to play!
So far I think it's an interesting change, because it really incentivizes munching a car, every now and then. All of this is also a question of balancing, of course: In return for the stamina cost, for instance, I will probably increase the damage that kicks and stomps will deal!
Punches don't use any stamina at the moment, because I don't want the stamina system to be too punishing. I think it would feel pretty bad to run out of stamina completely and then be stuck without any option to attack. But that's also one of the things I need to figure out exactly, still.
Maybe I will also add an option to "overcharge" your stamina: So if you eat more than what you would need to fill the stamina bar, you'd get a temporary damage/score multiplier, instead.
Just a small close-up to demonstrate updated animations for munching: To add some variation, the character will rotate the head a little between bites: Yum!

If you have questions or ideas concerning the stamina system, feel free to let me know! :)
