I wrote a NES game this weekend in 6502 assembly! I did this as a personal challenge to see how far I could get, and I'm pretty happy with the result. All of the art and audio (haha) was created over the weekend. Some base code I wrote earlier was used for vertical scrolling with collisions, and debugging that burned more jam time than I'd like to think about.
Tools used;
CA65/CL65 from the CC65 compiler
Nexxt nes graphics editor to draw all of the art.
Famistudio for the sfx. Didn't have time to write a song, sorry!
v0.1 fixes:
Fixed a hole in the water that the player could fall through. This was a hangover of me trying to implement a sprite 0 ui and needed a solid row of pixels on the edge of the screen
Made a dart trap slightly more obvious
Fixed a situation where it became impossible to solve the 'multiple fires on the other side of the screen' puzzle
Made it harder to softlock at the first fire. If you shoot a bubble on the floor below, it can x-wrap infinitely and you can't extinguish the flame. Added a ceiling bump to catch most shots fired this way.
