got a bit delayed, but completed day 6 and 7 of #AdventOfCode ("Trash Compactor" and "Laboratories") with #wasm WAT - reading vertical numbers was a bit tricky from WASM, but splitting lasers was fine
source+demo+writeup at same site as below

completed day 5 of #AdventOfCode ("Cafeteria") with #wasm WAT - this one's part 2 was another big rewrite but i did come up with an algorithm i really liked
source and demo for all parts at bracket.isageek.net/aocwat2025/

completed day 4 of #AdventOfCode ("Printing Department") with #wasm WAT - this one was actually really easy to translate to part 2, just needed a loop and to remove the rolls from memory
source/demo at same site as below

completed day 3 of #AdventOfCode ("Lobby") with #wasm WAT - this is the first one where i had to majorly rewrite for part 2

completed day 2 of #AdventOfCode ("Gift Shop"), again with handwritten WASM - a bit of trouble from numbers with nested repetition like 222222 but not too bad
source is on the same site as the last post below

remembered this year's #AdventOfCode and challenged myself to do it in hand-written WASM (WAT)
so here you go - bracket.isageek.net/aocwat2025
first day is currently done; I know day 2 is out but I'll do that later
