The player can move across fields and levels!

Easy and hard things weren't as expected:

Difficulties

• Get two input of the player in the same time: discovered SDL_GetKeyboardState, but what to do with a gamepad? This game will be keyboard only :)
• 1 + 1
• compilation in wasm with emcc while handling PNG files (first time I don't use BMP), USE_SDL_IMAGE=2 not enough, SDL2_IMAGE_FORMATS='["png"]' required. More than 2 hours lost checking what could be wrong in the code itself...
• Have now idea how to check if a player if stuck, except by running out of time or proposing a resign option to the player. AI? maths? Don't know how it could work??? 

Unexpectedly easy

• interaction player/obstacle
• basic animations

DONE

• Fields generation
• Obstacles generation
• Player 2D movement
• Interaction player / obstacle 
  • blocked
  • destroy
  • push
• Test: is it fun to play?? at least, it works. And yeah, with 1975 standards, its probably impressive and fun xD
• Inter-field space generation (change of strategy, extended array with entry and exit field)
  
• Obstacles generation animation
• Import some real data

TODO

From high to low priority.

• Understand that the player is stuck.
• Welcome menu
  • reuse functions from previous game
    
  • or not... would need it to propose new options depending on achievement
• Translations
  
• Test: what is needed for more fun?
  • special events? new powers?
  • Is it easy / fast / worth to code?
•  Interaction player / obstacle 
  • drag (useless?)
    
• field clear, level clear animations 
  • Would be very nice, but maybe too long to code ? 
• Aesthetic (-- ... hum ...) 
• Sound 
  • reuse functions from previous game but it takes so long to adapt the sounds, test in game...
• Sprites instead of uni-color tiles
  • uni-color maybe better than ugly sprites ;)
