I finally posted about my lastest js13k Games entry, Alley Kitty. It is mostly about technical stuffs and compression, but I am sure there are at least some who find these things interesting :)

Will ein kleines #Browsergame basteln, aber weder ganz pur mit HTML und #JavaScript arbeiten noch das ganz große Engine-Fass aufmachen.

Hab gerade die "Micro-Library" #kontra für mich entdeckt, die für die #js13kgames (#GameJam mit 13KB Größenbeschränlung) entwickelt wurde.

I am working on a blog post about my latest js13k Games game jam entry, mostly from a technical perspective.

I always wanted to see the numbers for each part at each stage - I am finally making it!

(But it is a lot of work and lot of words 😅 , these charts are ready and are interesting IMHO, so I wanted to share them even if I never finish the blog post in the end.)

Alley Kitty, my game for the js13kGames 2025 jam is live!

>> Play: https://js13kgames.com/games/alley-kitty <<

Check out the gameplay:

The game is open source, as usual:

I should probably just stop adding new sprites and objects at some point - preferably really soon 😅

I am now at 9146 of 13312 bytes (68%), but there's still some space for refactoring and optimization, and I think I even can cut a few stuffs.

Slowly coming together with the details, now it is even playable (and kind of fun!), it has character animations, music, transitions and other goodies - it starts to feel like an actual game!

Currently at 55% of the size limit (7345 of 13312 bytes used), still a lot of stuffs on the to do list!

After a late start a tiny game of a black cat might be forming after all :)

PS. there is still a lot to go but it might look familiar to some - that's probably not a coincidence.
