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.)

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.
