Update #2:
Didn't get as much done today, but still made some progress. Somehow completely forgot about walljumping during original movement coding, so added that. Also finished hazards, so only a couple more "objects" left to make. Main thing I did though was the title, which though I was lazy and made it simple was a nice weight to get off my back. Last thing is another fun 4x4 background tileset.
Tomorrow, plannng on making the level loading + transition system, plus the title music which I'm both excited and scared for (I'm not very experienced at making music, but I know some theory and I try my best.) Then I'll be ready for the fun part – levels.
