v1.4.0 - infloop be xwx

New stuff:

• New levels! New object sprites! Bug fixes! New sfx and music!
• lvl (condition) rules take into account what was on and around the level when you entered it, allowing for meta puzzling shenanigans.
• lvl be (property) now works for: GO ARND, MIRR ARND, ICY, ICYYYY, GO, GOOOO, YEET
• Tweaks to: copkat, snacc, slippers
• New properties: HAET is a conditional NO GO. BRITE/LIT/OPAQUE is a POWER/POWERED remix - a BRITE thing lights LIT things up, but only if nothing OPAQUE is in the way and float levels match. NO TURN prevents rotation except when moved through a portal. AN selects a random unit each turn. WURD is Baba's WORD - it makes the unit act like text for rule parsing purposes. HAET FLOR is the vertically inverted HAET SKYE.
• Making the whole level have a particle effect no longer tanks performance.
• LOOK AT dir/ortho/diag and BEN'T dir now work.
• x be every1 now works.
• XWX has an awesome glitchy effect.
• New INFLOOP rules - INFLOOP be :), XWX and TRY AGAIN have the corresponding effect if you form an infinite loop in the level. x be INFLOOP causes it to freeze and be unable to move (but still has all its rules otherwise).
• POOR TOLL now works with FLYE and SIDEKIK.
• GOOOO pushes stuff automatically, without the unit having to move first.
• TXT be ortho/diag now effects rules parsing.
• Rules parsing infinite loops are now detected and handled.
