Games seem to be getting bigger all the time taking up vast amounts of drive space but what can be done with very little resources? Quite a lot actually as the Quake homage Q1K3 has shown.

Developed for the js13kGames competition, where developers are given one month to create a game with HTML5 / JavaScript and possibly get a prize. The main constraint is that the file size limit for submissions is 13 kilobytes. It doesn't sound like a lot and not much bigger than a blank LibreOffice document.

One clever developer named Dominic Szablewski announced Q1K3 as their entry, which is a first-person Quake inspired shooter and it's actually quite amazing considering just how tiny it is.

Compared to most modern shooters and all the retro-inspired stuff it doesn’t really compare of course however I can’t help but marvel at it for the achievement. It’s another reason why I love things like PICO-8 , the cross-platform fantasy console that give developers many constraints and some great games have been made with it.

That said it does manage to squeeze in two levels, five different enemies, three weapons, thirty different textures, dynamic lighting, doors that open, a basic enemy AI and more.

You can play it here and see the source code on GitHub . See the entry on the competition site too.
