New Museum Level:
- Overhauled the Museum level art assets
- Completely new stealth focused level design: get to the book without being seen!
Other Changes:
- Nerfed slomo slightly: timescale is a bit faster. Also fixed some timescale related spaghetti
- Changed how bullet direction is calculated when reflecting enemy bullets: bullets flip direction rather than going in direction of crosshair
- Added full height window tiles (used in the Museum level)
