Hi players!
I just pushed a new version of the demo with a small but super important change. The demo was accidentally defaulting to the 'low' graphics settings which was only really meant to run on extremely old systems. ːsteamfacepalmː
It should now default to high, and we took out 'low' which had too many problems and wasn't enough of a performance improvement to justify the game looking that terrible and causing problems with puzzles.
