btw, just a little explanational code block to save you from trawling the docs

unforch I realised. oncollisionenter2d and oncollisionstay2d create gc and every once in a while you'll get a frame of unacceptable spike like 35ms
apparently.. you can just query contacts in fixedupdate and create your own non allocating collision methods...
dangerously close to doing it

when I gutted unity's input system it changed my entire outlook on the universe lol. just pressing the analogue stick there used 11.5 MILLISECONDS
rewrote it to use native calls.. 0.03 milliseconds

the most impresive thing of all is.. the actual highest use of CPU, more than the character controller, the physics, the rendering.. is the built in unity "Development Build" watermark

so, I decided to go ham on rude bear for a few weeks and make the best switch port ever because it was running at like.. 40fps and I didn't want it to ever get drop below 60
it's now running at like 200fps even on dev builds with deep profiling on

want to see something beautiful?
screenshot A, those highlighted blue bits show every time I touched the stick in unity's new input system it added 12 MILLISECONDS OF COMPUTE. 3/4 OF THE FRAME BUDGET ON INPUT
screenshot b, 0.03ms on input. beautiful. perfect

haha I got my best results ever 2 jams ago and now I don't think I'm ever going to be satisfied again until I come first

if it were depth I'd agree but I'm definitely about to play 100 games that look exactly like this if it wins

anyway, long story short, it's finally fucking done, one click PNG list to fonts
you'd think this technology would just exist and be a simple function in any font editor right? you'd think there's just an automator for this
well apparently not
(also please don't tell me if there is or I will cry)

and finally! after all these hours, it was done!
oh wait no I lied
I realised I had traced the nodes between the CENTRES of the pixels instead of AROUND the pixels so the shapes were all deformed

(still unsure if it's possible to get them to 64x64 but whatever)
then in unity I had to set up the internals so it would actually render like a pixel font at the right size instead of a blurry mess

then I had to write a python script inside font forge which would take each svg, parse out the unicode letter and convert them into glyphs
but then I realised that the em was 1000 so the glyph sizes were (n-1)*1000/64, so then I had to account for that to add the kerning space so it's pixel perfect

then I lower case j and i have multiple perimeters so I had to rewrite the file format to have store each shape as 1 perimeter and multiple destructive interior perimeters and then rewrite the svg parser for the third time

then I lower case j and i have multiple perimeters so I had to rewrite the file format to have store each shape as 1 perimeter and multiple destructive interior perimeters and then rewrite the svg parser for the third time
then the number 8 was broken because it only did the first hole. so I had to rewrite it to cache multiple destructive perimeters
then the second hole didn't work because it was hugging the bottom, so I had to adjust it to use the top left corner or it made a little square

and that.. went wrong a LOT. so to detect the interior lines properly I ended up having to do a flood-fill algorithm to check if there was a closed loop inside the perimeter, and then it could march around the insides (here's some fails)
