Pour 1 tablespoon of the oil into a large saute pan or skillet over medium heat.
In a medium bowl, toss the venison pieces with the cornstarch, salt, and pepper.
When the oil is hot, add the venison to the pan and cook until done, turning the meat over occasionally, for about 5 minutes.
Remove the meat and set aside.
Pour the remaining 1 tablespoon oil into the pan and add the garlic and ginger.
Cook for a minute or so, until starting to brown, then add the soy sauce, brown sugar, water, cumin, and red pepper flakes.
Cook the sauce for a few minutes until it begins to thicken a little, then add the venison back into the pan.
Cook for 1 more minute or so, stirring occasionally so that all the meat is covered equally with sauce.
Add more salt and pepper to taste if necessary before serving over a bed of rice pilaf.
