World’s Smallest Game Engine
Ғылым және технология
In 7 days, I tried to make a game with the weirdest game engine: PICO-8, a fantasy console that tries to emulate hardware restrictions of 1980s video game consoles like the NES (1985) and SNES (1991). I teamed up with the insanely talented, professional, full-time game dev and pixel artist @ReeceGeofroy, who created the game’s art, and in one week we were able to put together "String Quest," a retro dungeon crawler game where you navigate two players connected by a string. This was also our entry to the Brackeys Game Jam 2021.1, which had a theme of “Stronger Together,” and the mechanics were inspired by Murphy's Walk, a game I made for the Extra Credits Game Jam #4 in 2019.

top tip for collisions in pico 8: in the tile editor you can assign flags to a tile, then use the fget (i think) function to get the tile flags and check if it has the set "wall" flag you put on it. Saves you having to make a manual tile map table for every level edit: lets go with those likes and that heart!

this is a really cool and insightful style of video!
Really fascinating book recommendation for anyone who wants to learn more about retro game development is a book called "I am Error." The book goes into detail about how games were developed for the NES and how limitations were overcame with some really creative solutions. Another one I hear is good (but haven't read myself) is Racing the Beam which covers development for the Atari 2600. Anyways, cool looking game you guys, congratulations!!

I love the "pigo-8" console and all the games for it. It's so cool
While PICO-8 is fun, it's a far cry from being anything close to old school game programming. Even when using new-ish game programming libraries like DirectX5 or 7 which have more graphically advanced features than the PICO-8, it was absurdly harder than this, no comparison at all. Something that is closer and can be done with current hardware is making games in something like an ESP32 or ESP8266 (if you're up to the challenge) but that would only give you a taste, and from there you could go to some 8 bit microcontroller, although that wouldn't emulate the quirks of dealing with custom graphics chips older games used.

TIC 80 fantasy console is cool too (despite taking too much idea from Pico 8). BTW, at 8:12, you mentionned writing in code the coordonate of player spawn and enemy original position : wouldn't be easier to just use the tilemap for that?
Loved the video!

Hi, I know that you will probably not answer, but who knows. Could you make a video talking about how you got to your level of programming? All the journey, courses, books or whatever, how did you learn everything that you know and an effective way of doing it. If you don’t wanna make a video about it, if you have time, I would appreciate text version of your answer. I’m just so hooked to programming overall, but I don’t know where to learn all this stuff, I’m just doing some courses, watching videos etc. Love your videos and thank you in advance!
Simple and effective. Congrats!

I just wanted to point out, you could have used the second "joystick" that PICO-8 has for true 2-player. You can fork the project and make a copy with this mechanic.
