It's possible to shoot the gun sideways (or even greater angle) you just get more gas spraying out as liquid reaches the valve. Once upon a time, Western Arms even introduced mags with a sort of anti-siphon system (NLS) -- most commonly found in R-Type guns/mags -- that allowed you to shoot the gun at any angle without liquid getting to the valve.
Point in case, the more critical problem you'll encounter when shooting at angles is with hopup, as the BB will start curving "upward" ("up" as defined by your hopup being the top axis of your barrel) at a certain range, resulting in your shots taking off sideways.
So minimal hopup and whatever that entails.
