--          NES MUSIC BY RICHARD "KULOR" ARMIJO
--										TIC-80 CONVERSION BY KYUCHUMIMO
-- desc:    My first TIC-80 program

--WARNING: Saved on TIC-80 0.80.xxxx beta. Music doesn't work on previous versions.

--CHANGELOG:
--200621 - Some SPR and basic learning
--200622 - Added title music, letters tileset, timming
--200623 - Added mget command for collision proposes and poke() functions for change palette and create fade effect alike NES
--200624 - Added Horizontal and Vertical Alter ego sprite mirroring, SFX and 8x8 movement
--200625 - Added more tilesets, level HELLO WORLD and future levels rearranged based on ZX spectrum version
--200626 - Added Levels 2 to 9 and Remap function for animate tiles
--200627 - Added new formulas for X maps and stairs and blocks collision
--200630 - Added new formulas for Y maps, fall instrucction and sfx, animation and movement speed accurancy
--200701 - Added more level properties, climb movements and arrangement of debug data
--200702 - Added cover art for testing
--200703 - Added a definitive and noiseless cover art
--200804 - Added mset command for switch tiles (e.g. Bridges)
--200807 - Added music more accurated from source, instruments and music loops. Number of patern tables reduced to most minimum (7 saved).
--200808 - Added Sync command to restore tilemap. More variables for control, timing accurancy and small optimizations on code. Game over screen and music. Keyp command
--200820 - Added death proerties, sfx, level 3 music and music loop accurancy with formulas. Music command correction.
--200921 - Added both Pixel and phantom pixel collision, animation and sfx. Improved slide SFX and functional Game Over screen
--200923 - Palette values and address changed to hexadecimal. Code optimization and fixes on collisions and fall conditions (Size from 19618 bytes to 17506 bytes), bridge falling animation (fix later: overlay on frame)
--200924 - Bridge sprite set colorkey for alpha transparency, small fixes. Functional swap abillity for horizontal mirror added (With some unexpected bugs)
--200925 - Some transitions and timming added
--200928 - Vertical mirroring swap abillity added, more transitions and timming, some small changes or fixes.
--201101 - Added 6 levels more. Now you can press either A or B to swap between Alter Ego and Hero
--201105 - Added an unused music, there will be no more music due to limitations in the RAM size of music patterns on TIC-80. Minor additions
--201106 - Cover art updated to a better version. Now you will no longer be able to exchange places with Alter Ego if it is positioned on a block or platform. Added sound effects related to swapping
--201108 - Now each pixel has its own animation set and pixel animation timming accurancy
--201110 - 14 of 16 colors in the color palette updated to Sweetie 16 by GrafxKid palette for more consistency with TIC-80. Debug text thinner. Status are now displayed by tiles instead of sprites. Level clear message added at the end of every level
--201111 - Added pause function, new music respawn method. More additions. Bug fix: Freeze at swapping action bug fixed.
--201112 - Bug fix: Hero was not displayed when he was moving and the game was paused.
