Chrome dino game

TODOs

• make dino look like its running by continuously changing its sprite to point to the one with the left leg lifted and then the one with the right leg lifted
• rename sky.png to bg.png
• change dino.h/dino.c to use "tile" for the 8x8pixel squares in charblocks and "screenblock entry" for the 8x8bit pixel squares that are shown on the screen
• make floor look more realistic
• add cactus
• stop using magic numbers for cactus state
• get rid of unused variables in world.c
• figure out where to put cactus_state struct
• add collision detection if dino crashes into cactus
• make cacti spawn in random places
• fix collision detection to be less-square. right now if the bottom corner of the dino sprite which is just empty space hits the top corner of a cactus sprite, which is just empty space, that will count as a collision
• move cactus_left_lt_dino_right function
• maybe make cacti update object buffer
• run on an actual gameboy
• add game over screen
• dont do collision detection for cacti that are too far
• figure out how to remove & 0x01FF suffix from a buncha places, feels hacky
• maybe add gravity to dinosaur
• maybe add a way for hard presses to make dino jump higher and soft presses to lower
• add more floor tiles or make them spawn randomly so its harder to notice a pattern
• add score that increments
• save high score somehow
• add ability to pause and it opens a menu
• add clouds in second background
• add vultures
• make select change to dark mode
• add spy vs spy theme song

probably wont do

• figure out if there's a way to automatically determine the x_start/x_end/y_start/y_end of structs
