Fixed the following bugs:

• Delta Time now included for dashing (made combos easy for lagging computers)
• Progress bar will stop and resume while reviving if you have an extra life
• Music (hopefully) won't be interrupted with warning nor overlapping over levels
• Aim Lasers and Lasers's failsafe now work properly
