Celeste VS VVVVVV

Aha, found it! They opened sourced the C# version https://github.com/NoelFB/Celeste/tree/master/Source/PICO-8

forget TDD when you make a game, you want fast iteration time at all cost, gameplay is king, if you can't nail it fast enough, you'll make a bad game that is not fun

it's all about the feeling

Celeste's player class: https://github.com/NoelFB/Celeste/blob/master/Source/Player/...

https://store.steampowered.com/app/504230/Celeste/

check this out! both the readme and maddy's article that's linked towards the bottom, as well as the player.cs source code that is included. might be some decent resources

Keep in mind, the Celeste player controller is one single file of 5400+ lines of code.

So Celeste devs are shit at planning and have very poor code https://github.com/NoelFB/Celeste/blob/master/Source/Player/Player.cs

Celeste's source code is available in github :D https://github.com/NoelFB/Celeste It's a LOT of code, but some stuff in there helped me out creating momentum mechanics for a project recently.

Look at Celeste's Player.cs. Incredible games can (and often do) ship with messy code. Also read the readme where they discuss how they both agree and disagrees with criticism their massive file's received (look up the thread in this sub for a lot of it).

They dropped the controller script for Celeste. 5400 lines of tuning and refining to get everything right. https://github.com/NoelFB/Celeste

There's actually a README now, that does say it's probably messier than it should be and includes more cutscene logic than it should.

VVVVVV at least has since become open source.

VVVVVV - A platformer where you flip gravity instead of jumping. Was recently open-sourced to celebrate the game's 10th anniversary!

Yeah, just look at this beauty! https://github.com/TerryCavanagh/VVVVVV/blob/master/desktop_version/src/Game.cpp

Finally, games are really that complex. Check out for example Terry Cavanagh's blog post on releasing the source code for VVVVVV, and check out the source for Game.cpp (although keep in mind this was ported from ActionScript).

So it seems to be an unofficial policy rather than a written rule, if those allegations are true (remember that those are Wolfire's claims of what Valve said). Certainly there doesn't seem to be consistent enforcement - for instance Tales of Maj'Eyal is free, but $7 on Steam. Apparently there are some minor differences - does that mean that they can claim that it's a "separate version" and hence doesn't need price parity, even though 99.9% of the game is identical? There's also VVVVVV, which is open source (albeit years after initial commercial release) where you can freely build the exact same copy as on Steam ($5), including steamworks support. Does that count as a "separate version" when you just have to compile code? Admittedly these are two indie games, albeit extremely well-known ones, but then - isn't Wolfire Games also an indie studio?

I think it's worth noting VVVVVV has actually been open-sourced https://github.com/TerryCavanagh/VVVVVV
