Major Demo update: v0.5

This update to the demo brings it to a new level of polish and performance that we're very excited about. Things should look and feel a lot less janky than before. Here are the itemized notes for this update: [h2]New Features & Changes[/h2] [list] [*][b]You can now cancel your spell cast![/b] If you've already placed a perfectly-positioned Light, and you accidentally right-click, press escape to cancel the cast (while right-click is still held down). [*][b]New "Real Memory" post-processing effect[/b] for when certain scenes play out, such as the Pup-Pup scene on the back porch. [*][b]You can no longer jump in the Home.[/b] We decided to remove it because it didn't add anything interesting to the scenes, and only served to uncover & exploit collision bugs. [*][b]Add Poetry Plaques to the Temple.[/b] Written entirely in the rune language, deciphering these plaques adds an extra layer of depth to the story. [*][b]Diskettes now move to the bottom corner of the screen to dissolve.[/b] This doesn't have a major impact on the Demo, but has been put in place for future content starting in Chapter 2. [*][b]The staff animates out of the way when inspecting something.[/b] This is really just a workaround for some weird transparency issue with VHS tapes. [*][b]In-game menu now shows your current framerate.[/b] [/list] [h2]Improvements[/h2] [list] [*][b]The beginning of the demo has been completely polished[/b], with a better-looking UI and therapy hallway. [*][b]Cover up many imperfections in the Temple[/b], primarily where snow mounds intersect with other objects. The intersections should be much less noticeable now. [*][b]"Song of Innocence" is now more obvious[/b] and dissolves when inspected. This is a relatively important aspect of the story that a lot of players were missing. [*][b]Footstep System has been entirely rewritten[/b], and it should bug out less often. The new system requires significantly less manual setup compared to the old system. [*][b]Player breath now looks more realistic.[/b] [*][b]Game posters stick to the wall more believably[/b], and are anchored by their scotch tape now. Previously they were anchored semi-randomly, and looked a bit wonky as a result. [*][b]VHS tapes now slide into a sleeve before they dissolve.[/b] Similar to the staff animation issue above, this is also to get around a weird transparency issue with the tapes themselves. [*][b]Improve performance in Home scenes.[/b] Many thanks to the latest version of Unity for newly-added terrain features that made these improvements possible! [*][b]Slightly shrink the default reticle.[/b] It was just [i]ever so slightly[/i] too big for our liking. [/list] [h2]Bug Fixes[/h2] [list] [*]Shadow Creatures now properly render on top of (and underneath) other transparent things. [*]Objects that dissolve look much more realistic now; they were previously not correctly normal-mapped. [*]The Subtitle setting actually does something now, and defaults to Off. [*]Fix bug that caused Quality to show as "Low" even though it wasn't. [*]Fix bug that caused therapy door to sometimes not close. [*]Fix animation bug when staff un-hides (after teleporting to each next floor in the Temple) [/list]
