Post-jam patch! A lot of feedback was received about overall difficulty and various other matters, so hopefully this should address those issues somewhat. Not sure how much more I will tinker with this, but I'm glad to know the backend was structured well enough that dipping in to implement this wasn't as difficult as I was fearing.

Additions:

• Added checkpoints before each room 
• Added respawning
• Added new weapon: shotgun

Adjustments and Bugfixes

• Prevented player from accumulating damage from multiple sources in a single frame (unlike enemies)
• Added aim buffering out of player melee attack state
• Added additional impact feedback if when player takes a hit
• Reduced shot spread for normal shots and HMG shots
• Enemies now drop small weapon containers at the end of every wave
• Slight adjustments to tutorial text
• Hopefully fixed getting stuck in Mahou Shoujo time until overridden by another timeslow effect

Known bugs

• Sometimes the second-to-last enemy in a wave will also drop an item. I'm not sure why, but it's beneficial to the player, so whatever.
