Just a few bug fixes and gameplay tweaks in this one:
- Missiles now kill shielded enemies
- Boss doors attach a little later in 1st area (otherwise tedious for newcomers when stumbling in with vanilla weapons)
- Soft-lock fixes - spikey room and room respawner + switch combo (thanks Komeron)
- Added in-game tip, that if you get stuck inside switch blocks they'll automatically unswitch
- Fixed rare bug where gatling can appear multiple times
- Added enemy auto-kill if they somehow get outside room bounds and prevent room clearing (shouldn't be possible but better safe than sorry)
