The game doesn't have any invisible barriers... you might be expending dash energy.
-The code game isn't just for codes: That system boosts your movement/weapons and shields (if you got it) allowing you to jump higher (or run for longer)/charge more and recharge shields faster.
-Also, along the way, you should've picked up a grapple gun, which uses weapon energy... :)
There is a glitch with the jump system though, it is way too fast than it supposed to be. What is more baffling is that the jump strength is 0.1 - player can hold the jump as long as they have energy, and it applies on each tick (xWorldDeltaSec), so I kept it extremely low. I still might've broken something, so I'll be investigating it.
