Defender
#1
Another game I started working on but most likely won't finish. I think I just wanted to implement "wrapped scrolling" - the level is six screens wide, but you can still travel endlessly in any direction. It's an unfinished Defender (Atari 2600) clone Smile

Prevent the green aliens from obducting the dudes. The red spaceships just fly around randomly and shoot at you.

Edit  Attached the full game (denaalaafender.n7) from a post further down (denaalaafender.zip is the old version).

Very cool!! I have not seen this game in many years! If memory serves correctly, I didn't play very well back then either... lol

Much appreciate the memories!

Much appreciate the memories!

Maybe I'll finish it up after all this weekend. Lives, levels and ramped difficulty. I updated the zip because I realized it was quite annoying that the player ship "bounced" when hitting the ground.

"bounce" is good... better than "boom"... lol

Here's a more complete game, now with all assets generated in game. It requires atleast n7 version 24.01.19 Smile

Code:
' Denaalaafender
' --------------
' I've never played Defender. This game is just based on my memory of Youtube videos. For the fun
' of it, all assets in this game are generated by code.
'
' Use the arrow keys to move and spacebar to shoot
' Destroy all enemy spaceships to complete a level
' Try to help the humans from being obducted by the aliens
' You get bonus points for each human alive at the end of a level

It would take months for me to understand these "assets generated in game" , no external sounds, no external image files ... all resources are packed into one single Naalaa file .... It's super amazing  Big Grin Big Grin Big Grin

It inspired me to recreate Mario's character pixel-art using ImageFromMonoData function from your game. Voila !

Code:
#win32
set window "Mario - Pixel Art", 1, 1, false, 10

MarioImage = ImageFromMonoData([
