Demo update v0.9.1 — Golgalian Steam update #914134

The demo has been updated to version 0.9.1, complete with bugfixes for known issues and tiny reworks. Contents follow: Added: Tooltips in the options menu now clarify that mouse left-click and right-click also fire your main weapon and mortar, respectively. Changed: The game now defaults to 1280x720 resolution on first launch, and initializes at that size. Attempting to unpause while the options menu is open now closes the menu instead of unpausing. The SFX channel is now side-chained to the UI channel so power-up and extra life sounds are more audible. The tank's closebox is much larger to show off the feature more (try a controller!). Several sound effects have been reduced in volume. Reworked boss animations for the spiral shot and missiles. Boss missiles in phase 3 no longer fire infinitely (that was a bug). Increased player corpse health from 10 -> 15. Turrets should no longer spawn...
