Refreshed Demo~~~~

Uploaded a new demo, as promised.

Small bug fixes from yesterday's build:
- z-ordering fix for slimes
- disabled a state I had for testing purposes

Changes from the first demo:
- added controller support
- better game feel thanks to input buffer, modifier hitboxes
- bosses adjusted to feel better/more challenging/less bullshit, including some bug fixes like unintended shadows or flickering
- settings menu
- polished many animations and added VFX
- menus controllable with KB/controller(mouse only originally)
- more and better sound effects
