Update for demo v1.1.3 is here!

This patch brings significant changes to the demo with heavily modified levels and new challenges. Due to issues with gamepad, official support for this input method has been removed. It can be re-enabled in controls settings, but is disabled by default. I'll be looking at fixing and polishing gamepad controls in the future, but it's not currently a priority.

Changelog:
- official gamepad support has been removed
- official layout for Steam Deck has been added
- night levels have been significantly redesigned with bigger maps and fancier visuals
- crystal levels offer more interesting puzzles
- levels have different shapes now
- more visual variety
- level 5 from previous version has been removed
- bugfixes and other small changes
