Zone 3 release: "Sink"

I'm excited to announce the next zone, "Sink", has been released! The patch adds 9+ levels to the game, introduces an entirely new mechanic, and more!

Full patch notes:

New content

• Added a new zone, "Sink", featuring 9 (or more) entirely new levels. The zone must be unlocked by completing at least 6 levels in the previous zone, "Stack".
• Added a new mechanic: water tiles. I'll leave it up to you to discover in which ways they affect objects.
• Added a sound effect for the following actions:
  • Movement without pushing an object.
  • Pushing an object.
  • Pushing a door into a "stuck" position.
  • Transitioning between levels.
• The following additions contain heavy spoilers and as such will be in rot13:
  • Yriry qbbef abj nyfb unir n qvfgvapg tencuvp jura gurl nera'g "fghpx". Pbzcyrgrq yriry qbbef unir qvfgvapg tencuvpf sbe orvat pybfrq, obgu "fghpx" naq "hafghpx".

Minor changes & bug fixes

• Fixed unintended breaks in the following levels/zone. These should not affect their solutions.
  • "Shuffle"
  • "Tunnel"
  • "Pedestal"
  • "Swap"
  • "Stack"
• Fixed a bug where exiting or undoing out of "Swap" would incorrectly play certain music.
• Fixed a bug where the player character would teleport to their previous position before the level transition even started, when undoing through a level transition.
• Fixed a bug where undoing through a level transition would sometimes slide the level in the wrong direction.
• Fixed a bug where a button would sometimes be pressed or a door would sometimes be open when they shouldn't be, after an undo caused them to be unstacked.
• Fixed a bug where doors would incorrectly have the "stuck" graphic after an undo would place it on top of a stack.
• The following bug fixes contain heavy spoilers and as such will be in rot13:
  • Svkrq n oht jurer haqbvat jbhyqa'g cerfreir gur beqre naq qverpgvba va juvpu fzhttyrq vgrzf jrer chfurq vagb n yriry qbbe.

Still looking for a good way of showing door-button connectivity. I'm sorry it hasn't been resolved yet.

If you have any feedback, criticism, bug reports or other thoughts, I'd love to hear them!

Thanks for reading, and thanks for playing! <3
