0.4.0

Reworked 1st boss:

• Shortened boss downtime after tripping on destroyed pillars

• Added turrets in the upper right and upper left corners that will fire consistently at the player
  throughout the fight

• Made pillars respawnable due to the general increase in difficulty for the fight

New level:

• Added a “tutorial” segment to ease the initial experience with the game.

New enemy:

• The sniper enemy is nearly done and can be seen in level 3, my aim is to discourage overly cautious play.

Smaller fixes:

• Repositioned checkpoints in the first level

• Added some missing audio to the transition screen between level 1 and 2,
  also made it skippable with the space key

• Some fixes to bullets “lingering” after death, leading to “unfair” scenarios when spawning. Still WIP

Art:

• Changed depth of some objects to improve gamefeel

• Recolored/reworked the tank and its gunner to fit level 3 (winter level)

• Reworked the standard infantry enemies to fit level 3

• Added snow particles for level 3

• Finished up the final “victory” screen, a bit ahead of myself there but I felt inspired.
