boosting sideways was originally a bug.
in hawken, you can only boost forward and dodge sideways. being able to boost sideways is a quirk of how my code is written.
but the thing is.. i kind of like it! it essentially adds an extra movement option, kind of like strafing sideways pretty fast, which comes in handy sometimes. i have been reluctant to "fix" this behaviour for a long time, and i am seriously considering leaving it in as a feature of its own.
i WILL buff the side dodge to make it more worthwhile though, that's for certain
