Player movement: Oxygen dash

[jyee27]

Add a dash mechanic:

• Activates on left shift
  • Make sprinting the default and rebind walk to Ctrl? remove walking make walking activate when shooting or aiming
• Consumes 50%(?) of your oxygen bar on use
• When pressing a directional button, resets your momentum away from that direction and applies a directional force
• Holding jump+dash also goes upwards
• Neutral dash without jump goes forwards
• Make sure jumping while dashing at the right time makes you go really far

Dashing in combat:

• Hitting an enemy while dashing sends them flying instead of hurting you
• Add a freeze frame effect like Celeste and a lot of fighting games do when hitting an enemy.
  • We can reuse this for other effects. Call it something like SlowmoManager.cs
• Add an impact effect when hitting the enemy

Visuals:

• Add oxygen jetpack cloud effects when dashing or zero G moving

Considerations:

• How do we balance repeated ground dashing? More enemies and projectiles?
