Tweet Tweet Sky

Tweet Tweet Sky

My 6th annual #TweetTweetJam entry is:  Tweet Tweet Sky 🚀
An attempt to demake Low Mem Sky* in just 560 bytes (553 chars), using NO art assets!
*(...which was itself, a PICO-8 "demake" of No Man's Sky within a single PICO-8 cart)

CONTROLS

• ⬆️⬇️⬅️➡️  = Fly / Walk
• ❎                       = Land / Take off (when close to planet/station)
• ENTER / ⏸   =  Menu access to/from Galactic Map
  • (See below for details of *BONUS* companion TweetTweetJam entry!)

FEATURES

• 🌌 An explorable Galaxy - 7,153 units across
• 🌖 173 Planets*
  • Each planet with terrain, lakes & dwellings*
• 🛰 173 Space Stations*
  • (Tricky to dock - as always!)
• 🍎 Newtonian Physics*
• ✨ Parallax Starfield
• 🔥 "Realistic" Thruster*
• 🎞 60 FPS
  
• *(kinda, or as close an approximation of as I could do in 560 bytes
   - so alas, was not able to fit in: resources, aliens, etc. 😅)

"GALAXY MAP" COMPANION ENTRY!

• In addition to the original entry code below, I created a *BONUS* 2nd TweetTweetJam entry, which compliments this one
  ...an Interactive Galactic Map! 🗺
• Just like the good ol' days, when space exploration games like Frontier: Elite 2 came with a giant galaxy map poster (only this time, interactive!)
• (This might be the first time multiple TweetTweetJam entries were created to compliment each other? 🤔)
• MAP FEATURES
  • Generated names for all Planets and Space stations
  • Icons to indicate object type (Planet/Station)
  • Displays current player position 
    • (Itch page only feature - see Notes below)
• MAP CONTROLS
  • Mouse only

NOTES

• Below are the *actual* source codes for my jam entries
  (e.g. two standalone carts, with no connection between them)
• However, for this Itch page - I thought it'd be nice to add a way to quickly switch between the two carts AND (...by adding a little bit more "non-Jam" code...) to persist the ship position between carts.
• In my original jam entries (code above), the interactive map only indicates the player's starting position, but is still a useful reference (and can be fun to determine where you are in it by looking at nearby planets, JUST LIKE A REAL "PAPER" MAP!)
• I hope this makes things clear that these two entries can & do stand alone, and that I was not trying to abuse the "spirit" of TweetTweetJam (my fav in the calendar!) 😊
