Demo Update v0.9 - Challenges + Engine Update

Things are rapidly moving forward with patches 0.85 through 0.9 all in one (cause the former primarily had full-version improvements)! Watch out for an exciting announcement soon! :)

[h2]Patch notes (v0.9)[/h2]

• (Full version) Added challenge runs (unique pre-defined gameplay variants). For example, start with only a few shots but gain 1 shot per kill; or tons of huge explosions that insta-kill enemies but lots of extra enemies; or extra shots but sometimes they go backwards. :D
  
• (Full version) New item Black Hole: Pulls the closest enemy towards you when you fall into a hole. This brings the total to 111 items!
  
• Changed Demolisher to work on the first X obstacles you touch (X being the number of Demolisher items you have) and not just during the first turn to give you more freedom to use the item in a planful way.
  
• Changed Double Shot to trigger every other turn instead of only on the first turn since with the recent rework into a mini ball item it has lower immediate potential.
  
• (Full version) Made it possible to switch between unlocks in run-end screen when multiple items were unlocked in a run.
  
• Added tooltip to difficulty settings that shows all active difficulty effects.
  
• Prevented direct repetitions in item re-rolls from occuring.
  
• Excluded a few initially not very useful items from the random starting items pool for difficulty 15 and above.
  
• Added a few new sound effects.
  
• Added a few new icons and item graphics.
  
• Updated Unity engine to the latest LTS version. Primarily to ensure long-term compatibility, maintainability and (potentially) portability. You shouldn’t notice any difference except for maybe some performance improvements here or there.
  
• Optimized in-game lighting and added a third light quality setting.
  
• A bunch of general performance improvements and code cleanup.
  
• Several wording adjustments (shoutout to axerity).
  
• Countless smaller fixes and tweaks.

I hope you continue to enjoy the demo, and as always if you have any feedback please let me know via Discord or Twitter or leave a post in the Steam discussions!
