Thank you for explaining further :) Things can get a bit messy when there are a lot of bullets flying around.
I do like the Super Mario jump as well. Since Gunborg has a lot of challenging gunfights, I wanted to make sure that the player has a high level of control in air as well as on the ground. This way you can avoid bullets and other dangers more easily. As a result of this, the main character loses momentum quickly, as soon as you stop pressing right or left.
