Created for @griffpatch's December game jam! :D This isn't done yet and I could still polish this but the deadline's approaching so I'm sharing. The game is pretty laggy if you play it on Scratch since this is not optimized. Turbowarp is recommended for better experience: https://turbowarp.org/1100106701 Comment your best score! Controls: ←→ : move left/right ↑ : rotate clockwise ↓ : softdrop I also made mobile controls actually (it's in the code) but there isn't a button to turn it on lol Why this a Shape Shifter (theme of the game jam): The tetrominoes change shape = shift shape = shape shifter so this matches the theme (sort of xd) Credits: - Tetris99 (Nintendo) and tetr.io for sound fx - Sandtrix for tons of inspiration :) How this works: - cellular automata for sand physics (each pixel moves according to a defined set of rules) - uses flood fill for line clear detection Updates: 12/8 - added a new color (purple) 12/7 - shared! That's about it :p Thanks for reading!
